$2 Development Board Based On WinnerMicro W806 32-bit, 240MHz MCU

Shenzhen Hilink Electronics has released an inexpensive development board that utilizes the powers of the W806 MCU, a controllable IoT chip that offers high integration, low-power consumption, and low cost. The HLK-W806 development board which just hit the hardware market is based on the WinnerMicro W806 32-bit XT804 processor with 240MHz, inbuilt 1MB flash, and 288KB RAM. The board is equipped with an RST reset button, USB2.0 port, touch, UART, PWM, GPIO, SPI, I2S, ADC, and LCD interfaces. It is targeted to help IoT solution developers to evaluate W806 chips, realize more functions and build prototypes faster. The W806-based board is only debugged via the Ck-Link emulator since its MCU features Pingtou’s CDK development environment. Although not showing features of wired or wireless communication means, Hilink still promotes HLK-W806 as IoT MC.

As for the W806 MCU, Reddit says it is a RISC-V MCU using T-Head’s XuanTie E804 IP, but a user argues that XuanTie E804 is C-SKY ISA and not RISC-V. Another user also confirms that the MCU is not RISC-V and with that, it will likely be a C-SKY ISA. The reason is that C-SKY is mentioned in RISCV as a member of the RISC-V foundation with CPU architecture for low-power SoCs. And that the company does plumb C-SKY support into Linux/open-sources protocols and other toolchains.
