Handheld computing carrier board for a salvaged CPU module using a 100-pin mezzanine socket, with preserved 2S battery charging, balancing, and service-friendly edge I/O.
A buck boost converter that can be powered from a Li-Ion battery and output 3.3V @ 500mA. Powered by the TPS63051YFFR and in the same package as a standard Adafruit buck converter.
Expect to squeeze around 5-10% SoC from a typical Li-Ion battery.
Input Voltage Range: 2.5V to 5.5V
This is a LoRa remote control project built around a Raspberry Pi RP2040 SoC and the RFM95W LoRa module. The design includes user interface features such as multiple buttons and LEDs, power management components, and a temperature sensor. The project utilizes SPI, I2C, and USB interfaces for communication and control.

A BLE remote control board based on SoC ESP32-C3-MINI-1 that allows you to program as HID volume multichannel control, you can switch channels with the user button, or arrow keys.
Seeed Studio XIAO ESP32C6 is powered by the highly-integrated ESP32-C6 SoC, built on two 32-bit RISC-V processors, with a high-performance (HP) processor with running up to 160 MHz, and a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz. There are 512KB SRAM and 4 MB Flash on the chip, allowing for more programming space, and binging more possibilities to the IoT control scenarios.
