BL602
Bouffalo Labs BL602 microcontroller is a Wi-Fi and Bluetooth LE-capable microcontroller with a 32-bit RISC-V derived core. The chipset is designed for ultra-low-cost low-power applications and has support for 2.4G radio, Wi-Fi 802.11b/g/n and BLE 5.0 baseband/MAC designs. It also has support for a variety of safety and security features.
The BL602 microcontroller might not be able to stand side by side with the ESP8266 in terms of price but it definitely has more features, more memory, and more storage. We also learned that a Hong-Kong based organization known as Pine64 is currently making some efforts to reverse engineer the microcontroller for a fully open-source blob-free wireless implementation.
BL-63B IoT Module
Several boards have been built around this BL602 microcontroller like the DT-BL10 development board, the PineCone BL602 board, and the new BL-63B – a more compact module that offers many possibilities at a more favorable price.
The BL-63B is a highly integrated single-chip low-power 802.11n wireless local area network (WLAN) network controller. It has a low power consumption rate with high performance and support for various safety functions. The 17.3 mm x 15 mm x 3mm module also features a number of configurable general purpose IOs, which are configured as digital peripherals for different applications and control purposes.
