All profits are reinvested in the project: development, documentation, support.
No fuss, no guessing — just follow the essentials and get started with confidence.
Connect the power wires (6V–28V input) and plug in the USB-C cable using the included USB-C adapter board (with BOOT button).
Mount your Raspberry Pi Compute Module 4 (CM4) onto the carrier board, making sure it’s properly seated and aligned.
Press and hold the BOOT button on the adapter board while connecting the battery. Use the official Raspberry Pi Imager to flash the OS onto the CM4’s eMMC.
Once flashing is complete, disconnect the USB, power the board normally — your ochin_CM4v2 is ready to run.
