Challenger RP2040 WiFi Review – The Best Cheap WiFi Enabled RP2040 Board?

The Challenger RP2040 WiFi from Invector Labs is a Raspberry Pi RP2040 powered board in the feather form factor featuring WiFi connectivity. This is a really interesting board that comes in at an affordable price of $15. This features a USB-C connector. It also features a user programmable RGB Neopixel LED on the topside of the board. It has an on-board LiPo charger which can charge 3.7 or 4.2 volt LiPo batteries at up to 200mA. In many ways it acts just like the Raspberry Pi Pico, just with far more features - including a reset button! It measures in at 50.8 x 22.8 x 7mm.

The RP2040 chip supports 4 12-bit ADC channels (4 are user inputs and one measures internal temperature), two UARTs, two SPI and I2C controllers. It also has 8 PIO state machines, USB 1.1 host and device support and 16 PWM channels. Programming the Challenger RP2040 WiFi boards is exactly the same as programming the Pico. It can be programmed using the Raspberry Pi RP2040 SDK. Just press the boot select button whilst plugging the USB-C cable in and drag and drop the UF2 file onto the Challenger RP2040 WiFi. It will then reboot and run your program! It can also be programmed in MicroPython and CircuitPython.
