- K210 - CPU
|
|
- GD25LQ128D - 128Mbit w25qxx Flash chip (seems hardwired on SPI3)
|
|
- RY1303 - 3 Channel 5.5V 2A 1.5MHz DC/DC Step down PMU
|
|
- PT8211 - DAC audio (I2S)
|
|
- CH340C - USB to serial chip CH340. used to flash firmware over USB connector and console access on boards except for the Maix Go
|
|

|
|
- MSA300 - Accelerometer (I2C, address 0x26)
|
|
- STM32F103C8 - JTAG & UART, debug M1 without extra Jlink, this bypasses the CH340C on the module (USB to host, serial to K210)
|
|
- OV2640 - Color CMOS UXGA (2.0 MegaPixel) CAMERA C HI (DVP, SCCB address 0x60)
|
