About the PD65W Charger PCB

PD65W Charger is an open source RP2040/RP2350 PCB design by samanbeer, published on GitHub. It is a 2-layer board measuring 50.9 × 44.4 mm, with 28 components from 20 distinct parts.

Its main chip is the MOUDLE-SEEEDUINO-XIAO, from the RP2040/RP2350 family. Other key parts include the PD65W_MODULE, OLED_0.91-I2C, AP63205WU and INA226. By type, the board carries 9 resistors, 6 capacitors, 5 ICs, 3 connectors, 1 transistor and 1 diode.

It belongs with the power & battery and displays & leds designs in this gallery.

- What is it? It is a fast 65W charger with Power delivery, but its SMART! It has XIAO RP2040 MCU inside and if you want to know more then read more below! - What does it do? Belive or not its charging phone :O Well, it is also charging modern notebooks and all other things, that have USB-C, at a maximum power of 65W which is really good. And WHILE it is charging your device, the RP2040 is with help of INA226 chip measuring input/output Voltage and Current and displaing it on 128x32 display. Also all the chragers can be really hot while charging, but not this one. Why? Because this one has a…

PD65W Charger: common questions

What microcontroller does the PD65W Charger use?

The PD65W Charger is built around the MOUDLE-SEEEDUINO-XIAO, from the RP2040/RP2350 family.

How big is the PD65W Charger PCB?

The PD65W Charger measures 50.9 × 44.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PD65W Charger?

28 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the PD65W Charger design files?

From the samanbeer/PD65W_Charger repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the PD65W Charger design in my own project?

The repository has no license, so all rights stay with samanbeer. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PD65W Charger without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
