The Inventor 2350 W is a Pico 2 W-powered board for motors, servos, sensors, and sound, with built-in wireless connectivity for connected creations.
Inventor 2350 W is a multi-talented board that does (almost) everything you might want a robot, prop or other mechanical thing to do. Drive a couple of standardmotors(or fancy motors with encoders)? Yep! Add up to six servos? Sure? Attach a littlespeakerso you can make noise? No problem! It's also got abattery connectorso you can power your inventions from AA/AAA or LiPo batteries and carry your miniature automaton/animated top hat/treasure chest that growls at your enemies around with you untethered.
You also get a ton of options for hooking upsensorsand other gubbins - there's two Qw/ST connectors for attaching breakouts, three ADC pins for adding analog sensors, photoresistors and such, and three spare digital GPIO you could use for LEDs, buttons or digital sensors. Speaking of LEDs, we've also somehow managed to fit in 12 addressable LEDs(AKA Neopixels) - one for each servo and GPIO/ADC channel (or just use the whole lot for making rainbows, that's fine too).
Best of all though, is the brains of the outfit - the onboard Raspberry Pi Pico 2 W, which will give your creations 2.4GHz wireless connectivity.Use it to trigger your mechanical friends to do their thing remotely, or hook your robotic canary up to an API and report the air quality in your neighbourhood.

Getting Started
Our MicroPython libraries make it easy to get to grips with Inventor's hardware. You can download the latest Inventor 2350 W firmware at the link below. Copy the '-with-filesystem' .uf2 to your board to get the examples pre-loaded!
Measurements: 52mm x 66mm x 12mm (L x W x H). The mounting holes are M2.5 and 2.7mm in from each edge.
* The current limit of each motor can be disabled by soldering the "high current" pads on the rear. The maximum supported output current when unlimited is 0.7 A continuous (1 A peak) per motor.
** The direction indicators for each motor can be disabled by cutting the "motor LED" traces on the rear.
*** The battery voltage range is dependent on what functions you're using! Minimum voltages from our testing:
Motor driver stops working below about 2.9V
Audio stops working below about 2.2V
Pico stops working below about 1.9V
Max battery voltage is 5.5V, though we have powered from 5.6V, meaning rechargeable NiMH 4xAA packs can be used.
You can have a battery and USB connected at the same time safely. The board will use whichever power source has the higher voltage (usually USB).
Inventor 2350 W doesn't have battery charging circuitry onboard (this is so it's safe to use with either alkaline or LiPo batteries). You'll need an external LiPo charger (likeLiPo Amigo) to charge the battery.
If encoder motors are not being used, then four extra GPIO (16, 17, 18, 19) are available via the pads at the bottom edge of the board, in between the Qw/ST connectors and 0.1" motor connector.
