Custom V1 Engineering ESP32-DevKitC. * This build features a genuine Espressif ESP32-Wroom-32E-N8 (8MB) module, as well as a genuine CP2102. * Besides using the highest quality main chips, the extra USB UARTS have been broken out on the bottom of the boards for USB direct IO. * Green LED to match the Jackpot CNC Controller. * Micro-USB port.
