USB-UART converter with FT230XS and external 3.3V power supplyPrint

You can buy a lot of USB-UART converters e.g. with FT232, CH340 or CP2102. Each of USB-UART converters has some advantages or disadvantages.
Some doesn't have drivers inside kernel (linux) and/or windows. Another has a problem with faster communications.
I wanted to design own USB-UART converter and so I chose another IC for convert between USB and UART.
Broads is designed for beginners as one-sided PCB with a few jumpers.
I like IC by FTDI chip company. FT230XS.

ambiqmicro - Ultra-Low Power MicrocontrollerPrint

The Apollo family of microcontrollers from Ambiq Micro represents a quantum leap forward in the low-power MCU world. Power sensitive applications today are not looking for incremental reductions in energy consumption - they need revolutionary advances and the Apollo MCUs deliver. These highly-integrated microcontrollers offer industry-leading power numbers in BOTH active modes and sleep modes. Additionally, they offer the performance of an ARM Cortex-M4F core at power levels that are even lower than competing ARM Cortex-M0+ solutions. Unrivaled power savings combined with a high-performance processing engine make the Apollo MCUs an ideal solution for battery-powered devices and other power-sensitive applications.


Ultra-low active mode power consumption: 30?A/MHz (executing from Flash)
Ultra-low sleep mode power consumption: 100nA (with RTC on)
High-performance, 32-bit ARM Cortex-M4F processor
- Up to 24MHz clock frequency ...
