Electronics Lab Article: Grove Hat For Raspberry Pi Features A New RISC-V-Based AI Chip

Seeed Studio announced a Grove HAT for Raspberry Pi based on the Sipeed RISC-V MAix. This follows after Sipeed launched their 64-bit RISC-V MAix module, crowdfunding a series of boards on Indiegogo at the end of last year. The MAix module is based on Kendryte’s K210 processor, which features two 64-bit RISC-V CPU cores, each core with a built-in independent FPU, and 8Mb of SRAM. It is further equipped with an onboard neural network processor (KPU) for enhancing machine vision applications at up to 60fps for QVGA and 30fps for VGA. Also, there is an audio processor (APU) which supports up to 8 microphones at sampling rates up to 192KHz, with Fast Fourier Transform (FFT) hardware acceleration.
The Grove HAT has two versions that will be released. One is based on the Sipeed MAix-I with Wi-Fi, and the other version is without networking. Both boards can be utilized as a Raspberry Pi HAT, or function autonomously. The HAT is designed to offer an onboard 12-bit ADC, a display interface, a camera interface, and six Grove connectors—2×digital, 1×I2C, 1×UART, and 2×analog. Power option for the HAT will be through a USB-C connector. The HAT will utilize the Espressif ESP8285 to provide Wi-Fi support for the wireless version of the HAT.
