BL-63B – A smaller BL602 IoT module that sells for $1.5

Bouffalo Labs BL602 is a low-cost, low-power RISC-V microcontroller that provides 2.four GHz WiFi and Bluetooth LE connectivity for IoT initiatives at a value of round ESP8266. We first found it final yr, together with a improvement board.

Pine64 has developed its personal PineCone board that comes with the $ 2 PineNut module, and a few reverse engineering work has began with the BL602 SDK. However now there’s a smaller BL602 module with “Machine Intelligence” (that is the corporate identify) BL-63B that prices $ 1.5 at Taobao in China in addition to LCSC Electronics, though it is advisable to purchase 1000 to get that value, and the unit value is at the moment $ 2.5.

BL-63B WiFI and BLE module specs:

  • SoC – Bouffalo Labs BL602 32-bit RISC-V processor @ as much as 192 Mhz with 276 KB RAM, 128 KB ROM, 1 KB eFuse, WiFi and BLE
  • Reminiscence – 2MB Flash
  • Wi-fi
    • 2.four GHz 802.11b / g / n WiFI four 1 × 1 SISO as much as 65 Mbit / s (802.11n) or 26 Mbit / s (802.11g)
    • Bluetooth LE
    • PCB antenna
  • 11 pads and thru holes with
    • As much as 5x GPIO, UART, ADC, DAC, PWM, I2C, SPI, IR
    • Reset to default
    • three.3V and GND
  • Extra check pads for GND (2x), IO8 and IO5
  • Provide voltage – to three.6 V.
  • Dimensions – 17.three x 15 x three mm (DIP-11)
  • Temperature vary – -30 ° C to +85 ° C
  • FCC ID – 2AVTT-BL63B (Nevertheless it does not present up on the FCC web site but)

BL-63B pin assignment & dimensionsThere are additionally references to TYWE2S with BL-63B module. TYWE2S seems to be each a modular kind issue and an “RTOS platform that integrates all of the operate libraries of the Wi-Fi MAC and TCP / IP protocols” and can be used on Tuya’s ESP8285 module, making the BL-63B BL602 -Module could be a drop-in alternative with the identical pinout and firmware.
