Changelog

This is the list of changes since release v0.2.0:

Debugger

• Add support for ESP32 and ESP32C3.

wireless-esp8266-dap Release v0.2.0

Schematic

Consistent with the schematic of v0.1.4 .

Changelog

This is the list of changes since release v0.1.3:

Debugger

• Add support for elaphureLink

wireless-esp8266-dap Release v0.1.4

Schematic

The pins related to debugging (SWD and JTAG) are consistent with the schematic of v0.1.3 .

The pinout of the LED has been modified and there is now only one available LED to indicate the status of the WIFI connection.

The on-demand uart feature requires the previous(v0.1.3) LED pin and additional pin.
