Microcontrollers on boards using the TP4057
What boards using the TP4057 are built for
TP4057: common questions
Where can I find a TP4057 reference design?
Each of the 15 boards on this page is a real design using the TP4057. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the TP4057 use?
Most are built on ESP32 (6), RP2040/RP2350 (5), ESP8266 (1) and Nordic nRF (1).
How big is a typical board using the TP4057?
The median is 51 × 51 mm, and 40% are two-layer designs.
What is the most popular open source board using the TP4057?
By GitHub stars, PH60 by ph-design, with 154 stars.
Can I simulate one of these boards using the TP4057 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
