Features

This page needs to be properly filled according to the New Device Howto and the New Device Page guide.

Software Support

Linux and U-Boot upstreaming are in progress. See Allwinner_Nezha#Manual_build for build instructions. For U-Boot on the DevTerm, use the devterm_r_01_defconfig configuration.

Add-ons

On the back/bottom side are solder pads for a SPI flash, NAND or NOR. You need to add resistors in order to use it. The top left pin close to the edge is pin 1 (CS).

Carrier Boards

ClockworkPi's R-01 "core" module is pin compatible with RaspberryPi CM3 via DDR2-SODIMM 200 Pins interface.

Clockwork nomenclature

  • "core": such as R01, slots into a CM3 compatible interface on the "mainboard".
  • "mainboard": is the ClockworkPi v3.14 which accepts a "core" (R01),
  • "exp" - M.2 interface
  • "kit" - bundles together "core", "main", "ext", etc. Examples are DevTerm Kit R-01 and uConsole Kit R-01

ClockworkPi v3.14

This board features

  • PMU which supports reliable and complete lithium battery charge and discharge management
  • Integrated 5G-WIFI (802.11ac) + Bluetooth 5.0
  • High-gain antenna
  • 3x USB-A 2.0 interface
  • USB-C* charging port
  • TF card (Micro SD card) slot
  • 40 Pins MIPI screen interface
  • Micro-HDMI interface
  • 3.5 headphone jack, supports microphone input
  • Onboard stereo audio power amplifier chip
  • 40 Pins GPIOs expansion interface (using standard 0.5mm FPC connector)
  • 52 Pins extension module interface (using standard M.2 Mini PCI-E connector) for the “EXT. module”. Pins for UART are on this connector.

Schematics

Known Issue: DevTerm Kit: "UART" port on "ext" board is unstable or "read only"

DevTerm's "exp" board has electrical issues with the USB OTG UART. See:

Waveshare Compute Module PoE Board

Waveshare wiki

This board features a PoE ethernet port connected via USB to the module.

In addition, there are 3 micro USB ports for power supply, a built-in USB serial adapter, and USB host, as well as 4 USB-A host connectors.

Note that this board offers **no** access to USB0, which is the OTG/FEL USB port.

More connectors:

  • video: HDMI (Type A - full), 1x MIPI DSI, 2x MIPI CSI
  • audio: via HDMI, I2S
  • storage: µSD slot
  • fan header
  • 2 LEDs for power status and "Power ACT" (not applicable to the R01?)

Whether this laptop works with the R01 needs confirmation. It was designed for the Raspberry Pi CM3.
