Seeed Studio Studio Wio Lite W600 ATSAMD21 Wireless Development Board

You can program the board using the Arduino IDE. First, install the Seeed Studio SAMD Boards package via the Boards Manager. Then, select 'Seeed Studio Wio Lite W600' as your target board. Connect the board via USB Type-C, and you can upload sketches just like any standard Arduino. The board is fully compatible with libraries written for the Arduino Zero due to its identical SAM D21 core.

The operating current depends on the Wi-Fi module's state. With the W600 active and connected, expect currents in the range of 100-200mA. The SAM D21 microcontroller supports multiple low-power sleep modes, which can reduce the system's current draw to microamps when the Wi-Fi radio is disabled. For precise battery life calculations, consult the W600 and SAM D21 datasheets for specific sleep mode currents.

No, the Wio Lite W600 operates at a 3.3V logic level on all its I/O pins. Applying 5V signals directly to these pins can damage the microcontroller. To interface with 5V components, you must use a logic level converter or voltage divider circuit. Always ensure any connected peripheral is compatible with 3.3V logic or use appropriate bi-directional level shifting hardware for safe operation.

Connect a single-cell 3.7V LiPo battery to the onboard JST-PH 2-pin connector. The board includes a charging circuit that manages power input prioritization between USB and battery. When USB is connected, it powers the system and charges the battery. The charging current is typically set to a safe default, but specific charge rate details should be verified in the board's schematic available on Seeed Studio Studio's wiki.
