The WiDo is an Arduino Leonardo-compatible development board with built-in Wi-Fi, designed for Internet of Things (IoT) projects. It integrates a WG1300 Wi-Fi chip supporting 2.4GHz IEEE 802.11 b/g networks, along with a MicroSD card slot — both driven via SPI. An on-board 2.4GHz PCB antenna means no external antenna is required.
