Banana Pi has announced the BPI-Leaf-S3, a compact device powered by the Espressif Systems ESP32-S3. For reference, the chip utilises the Xtensa 32 bit LX7, which runs at up to 240 MHz, plus 512 KB of RAM. Additionally, Banana Pi has included 2 MB of SPRAM and 8 MB of flash storage; the only memory configuration in which the BPI-Leaf-S3 is available.
As CNX Software notes, the Espressif Systems ESP32-S3 provides Wi-Fi connectivity, with up to Wi-Fi 4 connectivity available (802.11 b/g/n). Moreover, the BPI-Leaf-S3 supports Bluetooth 5.0 Low Energy (LE) and has a PCB antenna. Separately, Banana Pi has equipped the BPI-Leaf-S3 with a USB Type-C OTG port, plus dual 22-pin headers that support 36x GPIO connections and USB serial, among other options.
Furthermore, Banana Pi has integrated a Nexopixel RGB LED, a feature that could be used to denote whether the system is operational. Currently, the 65.25 x 26 mm board is orderable for US$7.50 on AliExpress. Please note that the device's USB Type-C port supplies 5 V of power, although there is also a 2-pin connector for connecting a 3.7 V LiPo battery, should you prefer to use the BPI-Leaf-S3 away from a plug socket.
