Arduino Cinque Combines SiFive RISC-V Freedom E310 MCU with ESP32 WiFi & Bluetooth SoC

SiFive introduced the first Arduino compatible board based on RISC-V processor late last year with HiFive1 development board powered by Freedom E310 MCU, but the company has been working with Arduino directly on Arduino Cinque board equipped with SiFive Freedom E310 processor, ESP32 for WiFi and Bluetooth, and an STM32 ARM MCU to handle programming. Few other technical details have been provided for the new board, but since it looks so similar to HiFive1, I’ve come with up with preliminary/tentative Arduino Cinque specifications: MCU – SiFive Freedom E310 (FE310) 32-bit RV32IMAC processor @ up to 320+ MHz (1.61 DMIPS/MHz) WiSoC – Espressif ESP32 for WiFi and Bluetooth 4.2 LE Storage – 32-Mbit SPI flash I/Os 19x Digital I/O Pins 19x external interrupt pins 1x external wakeup pin 9x PWM pins 1/3 SPI Controllers/HW CS Pins I/O Voltages – 3.3V or 5V supported USB – 1x micro USB port for power, […]

Getting Started with ESP32-Bit Module and ESP32-T Development Board using Arduino core for ESP32

Espressif ESP32 may have launched last year, but prices have only dropped to attractive levels very recently, and Espressif has recently released released ESP-IDF 2.0 SDK with various improvements, so the platform has become much more interesting than just a few weeks ago. ICStation also sent me ESP32-T development board with ESP32-bit module, so I’ll first see what I got, before trying out Arduino for ESP32 on the board. ESP32-T development board with ESP-bit Module – Unboxing & Soldering One thing I missed when I asked for the board is that it was not soldered, and it comes in kit with ESP32-bit module in one package, and ESP32-T breakout board with headers in another package. The 21.5x15mm module is based on ESP32-DOWNQ6 processor with 32 Mbit (4MB) of flash, a chip antenna, and a u.FL connector. The module is apparently made by eBox, and also used in Widora board with […]
