Ai-Thinker’s new open source hardware platform. AiPi-Eyes-S1/S2 boards. It focuses on open source hardware. Let’s take a look at the features of AiPi-Eyes-S1 and AiPi-Eyes-S.
AiPi-Eyes-S1 is a development board specially designed by Ai-Thinker Open Source Team using Ai-M61-32S module, which supports WiFi6 and BLE5.3.
The Ai-M61-32S module equipped has rich peripheral interfaces, including DVP, MJPEG, Display, Audio Codec, USB2.0, SDU, Ethernet (EMAC), SD/MMC (SDH), SPI, UART, I2C, I2S, PWM, GPDAC, GPADC, ACOMP, GPIO, etc.
AiPi-Eyes-S1 integrates SPI Display Screen interface, DVP camera interface, external ES8388 audio codec chip and reserved TF deck, and leads out USB interface, which can be connected to USB camera.
AiPi-Eyes-S2 is smaller in size than AiPi-Eyes-S1 board. The main difference is it has one less set of audio channels because it uses an inbuilt audio circuit.

SPI touch screen interface
The SPI display interface is available on 30PIN FPC connector, and by default the board is configured for GC9307N color TFT Display + CHSC6540 touch screen controller, and the driver code is available.
DVP camera interface
Integrated DVP 24Pin camera interface is provided on board which is compatible with GC0308, GC0328 and other cameras, up to 200W resolution.
