uPesy ESP32 Wroom DevKit v2

The uPesy ESP32 Wroom DevKit v2 is a compact development board built on the ESP-WROOM-32E module, which houses Espressif’s ESP32 dual-core Xtensa LX6 processor with 4 MB flash and integrated 2.4 GHz Wi-Fi and Bluetooth 4.2/BLE. An onboard USB-to-serial bridge enables straightforward firmware flashing and serial monitoring via a USB-C connector, improving on older Micro-USB designs.
