Unlike all the other board based on RP2040, which use esp chip as the wireless interface . Picoduno use the CY43439 from infineon. The same chip like Raspberrypi pico w equipped with.

This is a raspberrypi pico w hardware in arduino form factor.

Unlike all the other board based on RP2040, which use esp chip as the wireless interface . Picoduino use the CY43439 from infineon. The same chip like Raspberrypi pico w equipped with.

Features:

1. totally compatible with arduino form factor.

2. fw developed for pico w can easily ported to picoduino without any change(especially all the wireless features).

3. using analog swith so that 3 ADC ports can connect to 6 pins from A0 to A5 on picoduino board.

4. use a dedicated voltage reference to improve the accuracy of the ADC.

5. use two DC-DC regulator instead of LDO to improve the efficiency as long as increase the maximum input voltage to 24V.

6. exposed all the GPIO from RP2040 chip.

7. USB type C interface.

8. all the deisgn files are open source and designed in Kicad.

9. The module is in LGA footprint and has a kicad package, which can be easily populated into other space limited PCB.

10. The module is a fix layer design without any trace underneath.

Specifications:

1. Microcontroller: rp2040 

2. Wireless : single-band 2.4GHz wirelss interface.( based on Infineon CY43439)

3. Interface: DC Jack and USB Type C

4. Operating Voltage3.3v

5. Input Voltage (recommended): 5-24v

6. GPIO: 26 multifunction GPIO. three of them are ADC capable

7. SWD debug interface

8. Clock Speed: 12 MHz

Limitataions

1. I'm not an antenna expert, so the antenna performance can only be regarded as accpetable. Not as good as the official pico w

2. In official pico w design. there are only three ADC pin that's available. So in order to compatible with arduino's pin definition, I use a analog switch to mux those 3 adc to totally 6 pins from A0 to A5.

3. There is no shiled cover for the module in this version yet.
