Free shipping starting at 50.–
This is a TTGO development board with 4x 5V relays which can be controlled wirelessly. The integrated ESP32-Wrover-B has full Bluetooth and Wi-Fi connectivity. The HRS4H-S-DC5V relays each have a blue status LED to show you if they are switched or not. The board is programmed via a USB-C port. It can also communicate via all common MCU interfaces like UART, SPI, I2C etc.
Info: Since there is no USB to serial chip on the module, you need a T-U2T USB to TTL adapter for programming. If you have already purchased this together with another display, you can of course use it for this one as well. The T-U2T USB to TTL automatic downloader is not included with the display.
