Yesterday Olimex wrote a blog post informing us that ESP32-CoreBoard was back in stock, one the many ESP32 boards launched late this year, but still hard to get. The company also mentioned they’d have limited quantity of the new ESP32-WROVER with JTAG and LCD display together with the picture below.
ESP32 is quite more powerful than ESP8266 so it makes sense to have an ESP32 development kit with an LCD display. A quick DuckDuckGo search led me to ESP-WROVER-KIT Getting Started Guide, where we can find more details including the overall specifications:
- Compatible with ESP-WROOM-32 and ESP32-WROVER modules based on ESP32 dual core Tensilica L108 processor clocked at up to 240 MHz with WiFi and Bluetooth LE connectivity
- Storage – Micro SD slot
- Display – 3.2″ LCD display connected via SPI
- USB – 1x micro USB port
- 8-pin UART header
- 6-pin SPI header
- 48-pin header for I/Os and camera interface (standard OV7670 camera module supported)
- Debugging – JTAG through USB interface (FTDI FT2232HL) or 14-pin header
- Misc – CTS/RTS jumper; power selection (EXT or USB); RGB LED; boot & reset (EN) buttons
- Power Supply – 5V DC input; 5V to 3.3V LDO chip
- Dimensions – 85.2 x 79.0 mm
The rest of the getting started guide explains how to configure jumpers to set the power source, serial flow control, and JTAG. It also shows how to access the serial console with a typical 115200 8N1 connection, as well as compile and load a simple hello program with ESP-IDF SDK in Windows and Linux.
Beside the development kit itself, I also discovered the new ESP32-WROVER module with the same feature as ESP-WROOM-32 plus an extra 32Mbit pSRAM chip and an external antenna connector.
The kit should be available in January based on Olimex’ blog post, but we don’t have any pricing info yet.
