The Radxa X4 is a small, low power (6 Watt) sbc with a form-factor very similar to raspberry pi 5, but it is based on a quad-core Intel N100 cpu supported by Ami UEFI bios and has a raspberry pi 2040 (pico) microcontroller on-board, to provide control of the sbc's 40 GPIO pins.
{{tip|
* Since this is actually an x86_64 "motherboard", despite the tiny size, the install procedure is basically the same as for any other x86_64. Follow the [[Handbook:AMD64|Gentoo Handbook:AMD64]]. The layout and procedures documented below show how this installation was performed, taking advantage of the "joetoo" ecosystem available to support a wide variaety of sbcs. Mini-PCs excluded, this is the first x86_64 sbc in the joetoo umbrella sbc project.
}}
Overall status: up and running. see performance section below Several RP2040 example programs validated; see two of them at [[User:Brendlefly62/Radxa_x4_N100_sbc_with_RP2040/Use_the_RP2040_Microcontroller|Use_the_RP2040_Microcontroller]]

=Board Specs=
== Hardware ==
X4 SBC, shwon in image to the right, mounted on cooler, with USB-C power (3A switched Raspberry Pi wall-wart PSU) and micro HDMI cable connected, and USB storage, USB keyboard/mouse dongle inserted. The device is actually shown inverted here, since the N100 cpu is mounted on the bottom of the sbc, and it is affixed to its cooler from "below", so the cooler can vent to open space above the device. For normal operation, the entire unit is turned over, to sit on 4 x rubber feet depicted in this photo. Note also visible in the picture are 128G NVMe M.2 stick, real-time clock battery, and wifi antennae. In this project, the nvme stick holds bootfs and rootfs partitions, with the luks-encrypted rootfs consisting of several lvm lvs unlocked and mounted via custom initramfs that resides with the kernel on the bootfs. The lunks encryption key can be provided by external usb storage device as shown here. Note also that the 40 x GPIO pins are controlled by an on-board Raspberry Pi RP2040 (pico).

The Radxa X4 is a small, low power (6 Watt) sbc with a form-factor very similar to raspberry pi 5, but it is based on a quad-core Intel N100 cpu supported by Ami UEFI bios and has a raspberry pi 2040 (pico) microcontroller on-board, to provide control of the sbc's 40 GPIO pins.
{{tip|
* Since this is actually an x86_64 "motherboard", despite the tiny size, the install procedure is basically the same as for any other x86_64. Follow the [[Handbook:AMD64|Gentoo Handbook:AMD64]]. The layout and procedures documented below show how this installation was performed, taking advantage of the "joetoo" ecosystem available to support a wide variaety of sbcs. Mini-PCs excluded, this is the first x86_64 sbc in the joetoo umbrella sbc project.
}}
Overall status: up and running. see performance section below Several RP2040 example programs validated; see two of them at [[User:Brendlefly62/Radxa_x4_N100_sbc_with_RP2040/Use_the_RP2040_Microcontroller|Use_the_RP2040_Microcontroller]]

=Board Specs=
== Hardware ==
X4 SBC, shwon in image to the right, mounted on cooler, with USB-C power (3A switched Raspberry Pi wall-wart PSU) and micro HDMI cable connected, and USB storage, USB keyboard/mouse dongle inserted. The device is actually shown inverted here, since the N100 cpu is mounted on the bottom of the sbc, and it is affixed to its cooler from "below", so the cooler can vent to open space above the device. For normal operation, the entire unit is turned over, to sit on 4 x rubber feet depicted in this photo. Note also visible in the picture are 128G NVMe M.2 stick, real-time clock battery, and wifi antennae. In this project, the nvme stick holds bootfs and rootfs partitions, with the luks-encrypted rootfs consisting of several lvm lvs unlocked and mounted via custom initramfs that resides with the kernel on the bootfs. The lunks encryption key can be provided by external usb storage device as shown here. Note also that the 40 x GPIO pins are controlled by an on-board Raspberry Pi RP2040 (pico).

The Radxa X4 is a small, low power (6 Watt) sbc with a form-factor very similar to raspberry pi 5, but it is based on a quad-core Intel N100 cpu supported by Ami UEFI bios and has a raspberry pi 2040 (pico) microcontroller on-board, to provide control of the sbc's 40 GPIO pins.
Tip* Since this is actually an x86_64 "motherboard", despite the tiny size, the install procedure is basically the same as for any other x86_64. Follow the Gentoo Handbook:AMD64. The layout and procedures documented below show how this installation was performed, taking advantage of the "joetoo" ecosystem available to support a wide variaety of sbcs. Mini-PCs excluded, this is the first x86_64 sbc in the joetoo umbrella sbc project.
Overall status: up and running. see performance section below Several RP2040 example programs validated; see two of them at Use_the_RP2040_Microcontroller

Board Specs[edit]
Hardware[edit]
X4 SBC, shwon in image to the right, mounted on cooler, with USB-C power (3A switched Raspberry Pi wall-wart PSU) and micro HDMI cable connected, and USB storage, USB keyboard/mouse dongle inserted. The device is actually shown inverted here, since the N100 cpu is mounted on the bottom of the sbc, and it is affixed to its cooler from "below", so the cooler can vent to open space above the device. For normal operation, the entire unit is turned over, to sit on 4 x rubber feet depicted in this photo. Note also visible in the picture are 128G NVMe M.2 stick, real-time clock battery, and wifi antennae. In this project, the nvme stick holds bootfs and rootfs partitions, with the luks-encrypted rootfs consisting of several lvm lvs unlocked and mounted via custom initramfs that resides with the kernel on the bootfs. The lunks encryption key can be provided by external usb storage device as shown here. Note also that the 40 x GPIO pins are controlled by an on-board Raspberry Pi RP2040 (pico).

Parsed HTML source of the new revision (new_html) | '<div class="mw-parser-output"><p>Construction of this page began 5 March 2025 (Work in Progress)
</p><p>The Radxa X4 is a small, low power (6 Watt) sbc with a form-factor very similar to raspberry pi 5, but it is based on a quad-core Intel N100 cpu supported by Ami UEFI bios and has a raspberry pi 2040 (pico) microcontroller on-board, to provide control of the sbc's 40 GPIO pins.
</p>
<div class="alert alert-success gw-box" style="padding-top: 8px; padding-bottom: 8px;"><strong><i class="fa fa-check-circle"></i> Tip</strong><br />* Since this is actually an x86_64 "motherboard", despite the tiny size, the install procedure is basically the same as for any other x86_64. Follow the <a href="/wiki/Handbook:AMD64" title="Handbook:AMD64">Gentoo Handbook:AMD64</a>. The layout and procedures documented below show how this installation was performed, taking advantage of the "joetoo" ecosystem available to support a wide variaety of sbcs. Mini-PCs excluded, this is the first x86_64 sbc in the joetoo umbrella sbc project.</div>
<p>Overall status: up and running. see performance section below Several RP2040 example programs validated; see two of them at <a href="/wiki/User:Brendlefly62/Radxa_x4_N100_sbc_with_RP2040/Use_the_RP2040_Microcontroller" title="User:Brendlefly62/Radxa x4 N100 sbc with RP2040/Use the RP2040 Microcontroller">Use_the_RP2040_Microcontroller</a>

<p>X4 SBC, shwon in image to the right, mounted on cooler, with USB-C power (3A switched Raspberry Pi wall-wart PSU) and micro HDMI cable connected, and USB storage, USB keyboard/mouse dongle inserted. The device is actually shown inverted here, since the N100 cpu is mounted on the bottom of the sbc, and it is affixed to its cooler from "below", so the cooler can vent to open space above the device. For normal operation, the entire unit is turned over, to sit on 4 x rubber feet depicted in this photo. Note also visible in the picture are 128G NVMe M.2 stick, real-time clock battery, and wifi antennae. In this project, the nvme stick holds bootfs and rootfs partitions, with the luks-encrypted rootfs consisting of several lvm lvs unlocked and mounted via custom initramfs that resides with the kernel on the bootfs. The lunks encryption key can be provided by external usb storage device as shown here. Note also that the 40 x GPIO pins are controlled by an on-board Raspberry Pi RP2040 (pico).
