XIAO RA4M1 32-bit Microcontroller Development Board 256KB Flash, 32KB SRAM, 8KB EEPROM Smallest Dev Board
Feature
- Popular Microcontroller Onboard: Powered by Renesas RA4M1, an 32-bit A.R.M Cortex®-M4 R7FA4M1AB3CFM MCU operating at up to 48 MHz with FPU, 256 KB of Flash memory, and 32 KB of SRAM.
- Highlighted Onboard Resources: Equipped with a 14-bit ADC, 12-bit DAC, CAN BUS, USB 2.0, and an onboard RGB LED.
- Expanded 8 New IOs: Adds 8 new IO pins on the back compared to previous XIAO boards (19 GPIOs in total), enabling more complex applications.
- Powerful Security Features: Built-in hardware encryption, secure boot, key storage, and other functions to ensure application security.
- Software Compatibility: Fully compatible with Arduino IDE for seamless project development and prototyping.
- Efficient Power Design: Offers 4 operating modes with power consumption as low as 45μA in deep sleep, and supports lithium battery charge management.
- Compact Thumb-Sized Design: Measuring 21 x 17.8mm, adopting Seeed Studio's classic XIAO form factor, ideal for space-conscious applications.
- Production-Friendly: Surface Mount Device (SMD) design with all components on the front and stamp holes on both sides, facilitating efficient mass production.
Being the 10th member of the Seeed Studio XIAO family, the XIAO RA4M1 remains the classic XIAO design (thumb-size, SMD, stamp holes). All these features make it a perfect fit for either space-limited projects such as wearables, or a production-ready module for your PCBA designs.
