ProS3

The ProS3 by Unexpected Maker is a highly capable ESP32-S3 development board designed to offer both power and flexibility for various applications. Notably, it comes preloaded with the latest version of CircuitPython that supports ESP32-S3, along with the UF2 bootloader. This feature enables you to update your ProS3 with the latest CircuitPython firmware easily. Once connected to a computer, the ProS3 appears as a USB flash drive, allowing for straightforward code transfer or direct editing on the drive. In terms of hardware, the ProS3 is well-equipped. It features dual 32-bit Xtensa LX7 cores that can run up to 240Mhz, accompanied by a RISC-V Ultra Low Power Co-processor. For connectivity, it supports 2.4GHz Wifi (802.11b/g/n) and Bluetooth 5, including BLE and Mesh networking. The board includes 16MB of QSPI Flash memory and an additional 8MB of QSPI PSRAM. It also incorporates two 700mA 3.3V LDO regulators, one of which is user-controlled and automatically shuts down in deep sleep mode. Further enhancing its capabilities, the ProS3 includes a low power RGB LED, ultra-low deep sleep current, and a USB-C connector with back-feed protection. It's also equipped with USB ESD protection, native USB plus USB Serial JTAG, and provisions for LiPo battery charging with a PicoBlade connector. The board offers 27 GPIO pins, including castellated headers and JTAG pins on the header, along with a 3D high gain antenna and a STEMMA connector powered by LDO1. The ProS3 supports not only CircuitPython but also Arduino, ESP-IDF, and has an early MicroPython port available, making it a versatile choice for a wide range of applications and development needs.
