Multi-cell battery manager unit with integrated charging, fuel monitoring, authentication and protection functions

The Texas Instruments (TI) bq40z60 device is a battery pack manager that integrates battery charge control output, fuel monitoring and protection functions to enable fully autonomous operation of 2- to 4-cell Li-ion and Li-polymer battery packs. This architecture enables internal communication between the gas-monitoring processor and the battery charger controller to optimize charge based on external load conditions and power path source management during system load transients and adapter current limits. The charging current efficiency is different for different power delivery external components such as NFETs, inductors and sense resistors.

MIMXRT1064-EVK: i.MX RT1064 Evaluation Kit

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.
