Ezsbc, an American embedded control solutions retailer, had produced a new development board that simplifies working with ESP32 module and makes it programmable via USB using the Arduino IDE.

The ESP32 is a low cost, ultra low power microcontroller with integrated Wi-Fi & dual-mode Bluetooth, which employs a dual-core Tensilica Xtensa LX6 microprocessor. ESP32 is created and developed by Espressif Systems for mobile devices, wearable electronics and IoT applications. It is a successor to the ESP8266 microcontroller.

Other than the ESP32 module, the board has an FTDI FT231XS USB to Serial converter, a 3.3V LDO, reset and flash switches and a multi color LED. The module can be programmed directly from the Arduino environment with 921600 bps upload speed.

It supports auto-download and will automatically be set in download mode by the downloader. Once the download is complete the board will be reset, just like a normal Arduino board.

Features of the ESP32 board:

  • 240 MHz dual core Tensilica LX6 microcontroller with 600 DMIPS
  • Integrated 520 KB SRAM
  • Integrated 802.11BGN HT40 Wi-Fi transceiver, baseband, stack and LWIP
  • Integrated dual mode Bluetooth (classic and BLE)
  • 16 MByte flash
  • 2.2V to 3.6V operating voltage
  • On-board PCB antenna
  • 3 x UARTs, including hardware flow control
  • 3 x SPI
  • 2 x I2S
  • 12 x ADC input channels
  • 2 x DAC
  • 2 x I2C
  • PWM/timer input/output available on every GPIO pin
  • SDIO master/slave 50 MHz
  • Supports external SPI flash up to 16 MB
  • SD-card interface support

The board is available for $17 on tindie store. Datasheet, documentation, and schematics are also available there.

Fantastic product. Works without trouble and the upload speed is fantastic. The Arduino environment makes programming a easy. I saw it here and I bought one of these modules because the price is right. Shipping to France took one week and cost less than $3.
