TP4057: common questions
Where can I find a TP4057 reference design?
Each of the 27 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.
What parts are used alongside the TP4057?
The RP2040, USBLC6-2SC6 and XC6206P332MR appear in the most repositories here.
Which microcontrollers do boards using the TP4057 use?
Most are built on RP2040/RP2350 (8), ESP32 (7), Nordic nRF (6) and AVR/Arduino (1).
How big is a typical board using the TP4057?
The median is 74 × 58 mm, and 52% are two-layer designs.
What is the most popular open source board using the TP4057?
By GitHub stars, Echoplayer by amachronic, with 279 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.
