i.MX RT1064 EVK is an evaluation kit for the i.MX RT1064 crossover processor, which uses NXP’s advanced Arm Cortex-M7 core implementation.

timer

In daily life, I think that in addition to clocks, set clocks are also very useful, such as cooking and steaming steamed buns. I want to make a low-cost, easy-to-use timing clock. It can be powered by 5VUSB charging wire. Use it for power supply, take it off when not in use.

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.

FreeEEG32: Affordable, stackable, open source, 32-channel EEG

FreeEEG32 is a stackable, open source, 32-channel, 24-bit, sigma-delta, simultaneous sampling board designed to meet the needs of scientists and brain hackers who require high-quality, affordable research-grade equipment. We have been developing this EEG for many years as we worked to create the ultimate open source solution to expensive proprietary EEG technology. FreeEEG32 combines four 8-channel AD7771 ADCs with ultra-low noise (<0.22 μV measured) sources and references, all driven by the powerful STM32H7 ARM Cortex-M7, while handling pre-processing. It's sensitive enough to handle high-quality EEG data collection and more.
