Sigh, copy the description and the internet thinks you're a spam site...  https://www.amazon.com/dp/B07S2RCT71?ref=ppx_pop_dt_b_asin_image&th=1 Description: TP5100 is a double switch buck 8.4V, single cell 4. 2V lithium battery charge management chip. Its ultra-compact QFN16 package and simple external circuit, making TP5100 ideal for portable equipment so large current charging management applications.Meanwhile, TP5100 built-in input overcurrent, undervoltage protection, over temperature protection, short circuit protection, battery temperature monitoring, reverse battery protection. TP5100 have 5V-18V wide input voltage, dual battery trickle charge into pre-charge, constant current, constant voltage three phase, pre-charge current trickle charge current through an external resistor adjustment, the maximum charge current up to 2A. TP5100 with a frequency of 400kHz switching mode makes it possible to use a smaller outer Suo device and the large current charging still maintain a

These are all purchase variations of this page.  The chip is the new 10 cent RISC-V.  https://www.tindie.com/products/johnnywu/nanoch32v203-development-board/ https://www.tindie.com/products/johnnywu/wch-linke-debugger/ nanoCH32V203 Development Board WCH RISC-V Dual TYPE-C USB Interface LCD Interface SD Card Slot Open Source nanoCH32V203 is a development board made by MuseLab based on CH32V203C8T6 of QinHeng. It features dual TYPE-C USB interfaces, LCD interface and SD card slot on board, and can be programmed through the USB port which is convenient for prototype verification and development. Dual USB interface, USB1 supports Device, USB2 supports Host/Device Can be downloaded directly via USB without additional downloader Onboard 8MHz and 32.768K crystal oscillator FPC-12P cable connector, which can support common LCD (such as ili9341, st7789, etc.) SD card slot, which supports SD card reading and writing (SPI protoc ol) Kit 3: nanoCH32V203 Development Board x 1 + 20 Pin Header x 2 +

And the original ESP8266 source code program can be used to transplant. ESP-M3 module core processor using cost-effective chip ESP8285. The chip integrates the enhanced version of the Tensilica's L106 Diamond 32-bit core processor with on-chip SRAM in a smaller package. ESP8285 has a complete Wi-Fi network function, both can be used independently, can also be used as a slave from other host MCU running. When the ESP8285 hosting application, can be started directly from the external Flash. Built-in cache memory facilitates system performance and optimizes storage systems. In addition, ESP8285 only through the SPI / SDIO interface or I2C / UART port can be used as a Wi-Fi adapter, applied to any microcontr

This QMK PCB is presoldered with Hot socket and RGB switch leds.If you are not familiar with QMK,we suggest you learn a little before ordering The switch we use is Gateron Pro Yellow which is POM stem and prelubed whose tactile feeling is much better than normal gateron yellow Gateron Pro Yellow is linear switches.Operating force is 50+-15gf.Total Journey is 4.0+0.4mm.Action stroke is 2+-0.6mm. When you replace switches in future,we suggest you use 3 pin SMD switches.If you want to use 5 pin switches,you ne
