Wio Link

Hardware

Platform Espressif 8266: ESP8266 is a cost-effective and highly integrated Wi-Fi MCU with built-in TCP/IP networking software for IoT applications. ESP8266 integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor and on-chip SRAM.

Microcontroller	ESP8266
Frequency	80MHz
Flash	4MB
RAM	80KB
Vendor	SeeedStudio

Configuration

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

[env:wio_link]
platform = espressif8266
board = wio_link

You can override default Wio Link settings per build environment using board_*** option, where *** is a JSON object path from board manifest wio_link.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:wio_link]
platform = espressif8266
board = wio_link

; change microcontroller
board_build.mcu = esp8266

; change MCU frequency
board_build.f_cpu = 80000000L

Uploading

Wio Link supports the following uploading protocols:

• espota

• esptool

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:wio_link]
platform = espressif8266
board = wio_link

upload_protocol = esptool

Debugging

Debugging currently does not support Wio Link board.
