A-Level Project that uses an ESP8226 MCU to process card transactions with an MFRC522 RFID reader aswell as a TFT 2.2 inch display to give information to the user.
A powerful LoRa expansion board based on the STM32WL55CCU6 MCU, designed to provide long-range wireless communication for embedded systems. Supporting I2C, UART, and SPI interfaces, this board can easily integrate with other MCUs in larger projects. Ideal for IoT applications requiring low-power, long-range data transmission.
VU3CER's non-RF-sensing, MCU controlled Simple T/R Switch with RX Grounding!
