DT-BL10 is a development board powered by BL602 WiSoC that sells for around $5. This board is specifically designed to work with a 32-bit RISC-V CPU with dynamic frequency from 1MHz to 192MHz. It has a 276KB SRAM and 128KB ROM.

The main focus of this board is on its wide range of wireless support. It has the support for Wi-Fi 4 802.11 b/g/n and Bluetooth 5.0 Low Energy. Wi-Fi security standards WPS/WEP/WPA/WPA2/WPA3 are available also with this low-power IoT application-focused board.

Moreover, a variety of security features such as secure boot, secure debug, XIP QSPI On-The-Fly AES Decryption (OTFAD), AES-128/192/256 are supported on this 49 × 26 × 3 mm board. Peripheral interfaces include SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, ACOMP, PIR, etc. Flexible GPIO configurations are supported. BL602 has a total of 16 GPIOs.

Targeted toward the well-established low-power IoT applications, this board tries to rival the ESP8266 and ESP32 solutions which are already very affordable and community-supported. It may take the heat off from this competition with the implementation of the BL602 SoC. Time will tell if it can make an impact in the maker community.
