CaribouLite RPi HAT: Fully open source dual-channel SDR Raspberry Pi HAT with tuning range up to 6 GHz (schematic, PCB, source code, etc.)

CaribouLite is an affordable open source dual-channel software-defined radio (SDR) platform and an SDR-focused FPGA development framework implemented as a Raspberry Pi (RPi) HAT. CaribouLite turns your Raspberry Pi single-board computer (SBC) into a standalone dual-channel radio Tx/Rx with a tunable spectrum up to 6 GHz. CaribouLite gives you complete control over its hardware, including FPGA, firmware, and all supporting software. With the deeply integrated IceStorm toolchain, writing your own FPGA applications couldn't be easier. You can reuse many Verilog modules, such as the SPI and SMI modules, to support custom applications for CaribouLite hardware.

CNC DCDC converter

This design is a digitally controlled DCDC converter. MCU is used to control the output voltage of the DCDC converter to achieve the purpose of numerical control. Considering the time and cost, finished modules are used for verification. This design idea is simple and reliable. And it has the advantages of low cost and high flexibility. The function to be realized is to control the output voltage of the DCDC module with buttons and digitally display the voltage and current values.
