Pimoroni Pico LiPo - 16MB

Pimoroni created a top of the line Pirate-brand RP2040-powered microcontroller with lots of flash memory, USB-C, STEMMA QT/Qwiic and debug connectors... and built in LiPo charging!

Pimoroni Pico LiPo is powered and programmable via USB-C and comes with 16MB of QSPI (XiP) flash. Pimoroni made it super easy to connect to things solderlessly too - there's a Qwiic/STEMMA QT connector so you can hook up a whole host of different sensors and breakouts, and a debug connector for if you want to do your programming using a SWD debugger. There's also an on/off button and a BOOTSEL button, which can also be used as a user switch.

Pimoroni Pico LiPo also has onboard LiPo/LiIon battery management - the inbuilt charging circuitry means charging your battery is as easy as plugging your Pimoroni Pico Lipo in via USB. There's two indicator LEDs connected to the battery circuit to keep you informed of on/off state and charging status and it's compatible with any of our LiPo and LiIon.

Programmable with C++, MicroPython or CircuitPython, Pimoroni Pico LiPo is the perfect powerhouse for your portable projects.

About the pinout

• There's a handy interactive pinout for this board at pico.pinout.xyz.
• The user LED is wired to GP25, just like on an ordinary Pico. You can blink it in exactly the same way!
• As well as being useful for putting your Pimoroni Pico LiPo into bootloader mode, you can also use the BOOT button as a user button. It's wired to GP23 and active low.
• You can read GP29 to monitor the voltage of the battery (and use that measurement to calculate how much charge is left in it). This example shows you how to do that in MicroPython!

Notes

• The power button can also be used as a reset button, yay! Just double press it to cut and reinstate the power whilst holding down the BOOTSEL button on the Pimoroni Pico LiPo to get into bootloader mode, with no plugging and unplugging of cables required.
