Wio Lite RISC-V WiFi Board with ESP8266 Module Launches for $6.9

Wio Lite RISC-V

Released this summer, GigaDevice GD32V generated a lot of buzz, as a cheap general-purpose 32-bit RISC-V MCU, and soon after the $5 Longan Nano development board with LCD display and enclosure was launched to the market. However, many applications benefit or require some network connectivity with WiFi. Espressif Systems is a founding member of the RISC-V Foundation, so RISC-V WiSoCs (Wireless SoCs) are coming, but AFAIK none of those are available yet. In the meantime, Seeed Studio has launched Wio Lite RISC-V board which brings WiFi connectivity to GD32V MCU through an ESP8266 WiFi module. Wio Lite specifications: MCU – Gigadevice GD32VF103CBT6 RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM Wireless Module – ESP8266 WiFi Wio Core with 802.11b/g/n/ WiFi 4 connectivity Storage – MicroSD card slot USB – 1x USB Type-C port for power and programming Expansion – I/O headers for GD32 MCU, I/O header for […]

$5 Longan Nano GD32V RISC-V Development Board Comes with LCD Display and Enclosure

Longan Nano

There’s been some exciting news about RISC-V microcontrollers recently with Gigadevice announcing GD32V, one of the first RISC-V general-purpose microcontrollers, which outperforms its Arm Cortex-M3 equivalent in terms of performance and power consumption. The company also announced some development boards, but they are not quite that easy to purchase being listed on Tmall website in China. The good news is that Sipeed has introduced Longan Nano development board powered by GD32VF103CBT6 microcontroller, and it’s up for sale on Seeed Studio for $4.9. Longan Nano board specifications: MCU – Gigadevice GD32VF103CBT6 32-bit RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM Storage – MicroSD card slot Display – 0.96″ 160×80 IPS RGB LCD connected via SPI USB – 1x USB Type-C port for power and programming Expansion – 2x 16 through holes (2.54mm pitch) exposing 3x USART, 2x I2C, 3x SPI, 2x I2S, 2x CAN, 1x USBFS (OTG), 2x […]
