[CNX-Software] - Waveshare ESP32-S31-Zero – A tiny ESP32-S31 board with up to 32MB PSRAM, 32MB SPI flash

Waveshare ESP32-S31-Zero is a small ESP32-S31 development board that follows the form factor of the earlier Waveshare “Zero” boards, such as the ESP32-C6-Zero-B, RA4M1-Zero, and ESP32-S3-Zero, among others. The new tiny board still features a USB-C port for power and programming, as well as eighteen through and castellated holes for GPIO and power signals,  but it boasts a more powerful ESP32-S31 dual-core RISC-V MCU clocked at up to 320 MHz, featuring 2.4 GHz WiFi 6, Bluetooth 5.3, and 802.15.4 connectivity, as well as up to 32MB on-chip PSRAM and a 16MB or 32MB SPI flash chip. Since the ESP32-S31 has quite a few extra I/Os, Waveshare also added a 40-pin high-density connector for LCD, touchscreen, SD card, USB 2.0, and extra GPIOs.
