Seeed Studio XIAO RP2040 Plus

RP2040 power without turning your project into a flying breadboard. The XIAO RP2040 Plus packs a dual-core 133 MHz MCU, 15 extra SMD GPIOs and onboard Li-ion battery management into Seeed's tiny 21 × 17.8 mm footprint.

Why You Want It

It is a compact route into the huge RP2040 ecosystem, complete with PIO state machines for the oddly specific timing jobs that normally become a late-night firmware problem. Extra I/O and battery monitoring make the Plus version far more comfortable in wearables, sensor nodes, robots and custom PCBs.

Specifications

• MCU: Raspberry Pi RP2040 with dual ARM Cortex-M0+ cores at up to 133 MHz
• Memory: 2 MB onboard Flash and 264 KB SRAM
• GPIO: 29 total, including 26 digital, 4 analogue and 26 PWM-capable pins
• Extra I/O: 15 additional GPIOs on 1.27 mm SMD castellations
• Interfaces: 2× I²C, 1× UART and 1× SPI
• USB: USB Type-C
• Battery Management: Onboard PMIC with Li-ion charging and software-controlled battery-voltage monitoring
• Battery Monitoring: GPIO24 enables sensing; GPIO29/A3 reads battery voltage
• Onboard Controls: Reset button and Boot button
• Indicators: User LED, charge LED and programmable RGB LED
• Input: 5 V by USB Type-C or BAT input
• Dimensions: 21 × 17.8 mm (small board, suspiciously long project list)
• Operating Temperature: -20°C to 70°C
• Software Support: Arduino, PlatformIO, MicroPython, CircuitPython, C/C++ SDK, TinyGo, Rust and Zephyr

What's in the Box*

• 1× Seeed Studio XIAO RP2040 Plus
• 2× 7-pin headers

Disclaimer

*Battery and USB cable are not included. PIO can solve many timing problems, but it cannot stop you starting three new projects before finishing the first one.
