The ME16WS04 is a high-performance, low-power, and cost-effective dual-band WiFi 6 2.4G/5Ghz, BLE 5.4 module based on the BK7239N SoC. It features an ARM core STAR-MC1 RF transceiver with a core operating speed of 240MHz, along with 4MB SiP FLASH programmable space, 512kB RAM, an integrated 2.4GHz/5G transceiver, and other powerful supporting resources, providing a perfect solution for WiFi and Bluetooth coexistence. The BK7239N supports protocols such as 802.11a/b/g/nax, BLE 5.4, and IEEE 802.15.4. Its range in open spaces is estimated at up to 150 meters.
