JTAGulator copied from Joe Grand design. Allows to discover JTAG interfaces on embedded systems. Also allows to find UART interfaces. Is able to use OpenOCD to debug chips.

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
