●Support STA、SoftAP、STA+SoftAP and sniffer mode
●Dual-core 32-bit RISC-V CPU with FPU and DSP, the highest frequency can reach 320M
●532KB SRAM，128KB ROM，4Kb eFuse
●Integrated RF Balun、PA/LNA
●Support XIP QSPI On-The-Fly AES Decryption (OTFAD)
●Support TrustZone
●Support AES-CBC/CCM/GCM/XTS mode
●Support MD5、SHA-1/224/256/384/512
●Support TRNG (true random number generator)
●Support for PKA (Public Key Accelerator) for RSA/ECC
●Support Wi-Fi Quick Connect with BLE
●General AT commands can be use convenient
●Support secondary development, Windows, Linux environment

Peripherals: DVP、MJPEG、Dispaly、AudioCodec、USB2.0、SDU、Ethernet (EMAC)、SD/MMC(SDH)、SPI、UART、I2C、I2S、PWM、GPDAC、GPADC、ACOMP and GPIO

AiPi-Eyes-S1 a development board integrates SPI screen interface, DVP camera interface, with external ES8388 audio codec chip（Ai-M61–32S module also have built-in audio circuit）, reserved TF card slot, and leads out USB interface, which can be connected to USB camera.

AiPi-Eyes-S2 a development board only uses a built-in audio circuit, so it will be smaller than AiPi-Eyes-S1 and have one less set of audio channels.
