This project is a communication device designed with Adafruit's 3857 Microcontroller (U1) and Hoperf's RFM95W-915S2 RF module (U2). The microcontroller interfaces with the RF module via SPI protocol for wireless data transmission. The project also includes a capacitor (C1) and an SMA connector (J1). #LoRa #IoT #project #M4 #Adafruit

A circuit for a gps tracker using stm32f103c8t6 and sim 808, that acquires and sends gps coordinates to a separate interfaced application. The circuit will be powered by a 12v dc battery so there a need for power regulation. there is a USB type micro B for code uploading.

3.7V Lipo Charger. Interfaces with MT3608 Boost Converter to convert 3.7V to 5V. Slot on top of your Arduino and charge your battery while the Arduino is plugged in. Or run your Arduino portably using the battery.

The "Green Dot 2040E5" Board is a Node that interfaces RS485 Sensor probes and can log information to the cloud using LoRa Connectivity. It uses the XIAO RP2040 and the LoRa-E5 (STM32WLE5JC) modules from Seeed Studio to do its magic. It also has amazing power management capabilities (Solar charging, Battery protection, etc) that make it very useful for IoT applications #Seeed #XIOA #LoRa #RP2040 #IoT
