Wi-Fi and Bluetooth MCU module integrates an ESP32-D0WD-V3 dual-core 32-bit LX6 processor with 16 MB Quad SPI flash. The module supports IEEE 802.11b/g/n at 2.4 GHz up to 150 Mbps and Bluetooth v4.2 BR/EDR plus Bluetooth LE. It operates from a 3.0 V to 3.6 V supply across a -40 °C to 85 °C ambient temperature range. The 18 mm by 19.2 mm by 3.2 mm module provides 38 pins, up to 26 GPIOs, and an IPEX connector for an external antenna.
