OLIMEX ESP32-EVB

Hardware

Platform Espressif 32: Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

Microcontroller ESP32
Frequency 240MHz
Flash 4MB
RAM 320KB
Vendor OLIMEX

Configuration

Please use esp32-evb ID for board option in “platformio.ini” (Project Configuration File):

[env:esp32-evb]
platform = espressif32
board = esp32-evb

You can override default OLIMEX ESP32-EVB settings per build environment using board_*** option, where *** is a JSON object path from board manifest esp32-evb.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:esp32-evb]
platform = espressif32
board = esp32-evb

; change microcontroller
board_build.mcu = esp32

; change MCU frequency
board_build.f_cpu = 240000000L

Uploading

OLIMEX ESP32-EVB supports the next uploading protocols:

  • esptool
  • esp-prog
  • jlink
  • olimex-arm-usb-tiny-h
  • olimex-arm-usb-ocd-h
  • olimex-arm-usb-ocd
  • olimex-jtag-tiny
  • iot-bus-jtag
  • tumpa
  • minimodule

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:esp32-evb]
platform = espressif32
board = esp32-evb

upload_protocol = esptool

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

OLIMEX ESP32-EVB does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
