(SPIDER Automation) Seeed Studio Wio Lite MG126 Development Board | SAMD21 ARM Cortex-M0+ with MG126 2.4GHz Bluetooth Module & Feather Form Factor

SPIDER Automation Seeed Studio Wio Lite MG126 Board | SAMD21 & MG126 Bluetooth

Description

SPIDER Automation Seeed Studio Wio Lite MG126 is a cost-effective, feather-compatible development board built around the SAMD21 microcontroller and equipped with an onboard MG126 Bluetooth module. The core SAM D21 is a high-performance 32-bit ARM® Cortex®-M0+ microcontroller operating at 48 MHz, while the MG126 functions as a dedicated 2.4GHz single-mode Bluetooth low energy transceiver. Sharing the same core architecture as the Arduino Zero and matching the widely adopted Adafruit Feather form factor, this board offers exceptional expandability and direct compatibility with existing Arduino libraries and shields.

Engineered for portable and low-power IoT applications, the board breaks out the 3.3V I/O resources of the SAM D21, providing 14 digital pins, 6 analog input channels, 1 UART port, 1 I2C port, and an ICSP header. Modernizing connectivity, it features a reversible USB Type-C interface for data transmission and power, alongside a JST2.0 Li-Po battery connector supporting 3.7V to 4.2V rechargeable cells. The MG126 Bluetooth core communicates with the SAMD21 via high-speed SPI (up to 4Mbps) and features configurable packet-handling engines, adjustable TX power, and integrated channel filtering for reliable wireless operation up to a 10-meter range.
