A simple microcontroller built around the RP2040.
- Redesigned board layout
- Doubled headers
- Dip switches and SD card slot connected to GP13-15 and GP16-19+29 respectively
- Better power system and circuit design
- Replaced 2020 Neopixel with more available 5050 footprint.
- Fixed seperation between 1v1 and 3v3 power planes.
- Better positioning and tracing of the components to improve overall signal integrity.
- Added a regular LED to keep it somewhat compatible with regular Pico SDK Code.
- Modified USB C port to be THT Mounted rather than completely SMD.
- Moved GPIO 29 from VSYS Sense to an exposed pad on the bottom side of the PCB.
| Stat | Raspberry Pi Pico 1 | Picopowered V1-RP2040 |
|---|---|---|
| Flash | 2MB | 16MB |
| Reset Button | No | Yes |
| LED | Yes (1 Color) | Yes (RGB Neopixel) |
| User GPIO Button | No | Yes |
| USB Type | Micro-B | C |
- Linear regulator requuires minimum of 3.3 Volts, unlike Pico's buck boost converter which can be powered by 1.8 Volts.
No ADC_VREF (connected to GND instead) because the power by linear regulator is filtered already.ADC VREF now works with picopowered V2 and V3- No Power Mode selection (stems from power supply used)
Most of the disadvantages occur only due to the Pico's superior power supply system, but the system on the PicoPowered board is more filtered and smooth.
