  • K210 - CPU
  • GD25LQ128D - 128Mbit w25qxx Flash chip (seems hardwired on SPI3)
  • RY1303 - 3 Channel 5.5V 2A 1.5MHz DC/DC Step down PMU
  • ESP8285 - WiFi module (serial)
  • 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
  • MSM261S4030H0 - Microphone (I2S)

Maix Go

On-board

  • MSA300 - Accelerometer (I2C)
  • 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)

External

(source: schematic)

  • ST7789V - 240RGB x 320 dot 262K Color with Frame Memory Single-Chip TFT Controller/Driver (SPI)
  • NS2009 - 4-Wire Touch Screen Controller (I2C)
  • TF card slot (SPI)
