The EXPANDER mode allows the Bus Pirate to communicate with an external ESP32 Bus Expander device.

The expander acts as a radio coprocessor, extending the capabilities of the main Bus Pirate firmware, notably by adding 5 GHz Wi-Fi support.


⚡ Flash it

Use the ESP32 Bus Pirate WebFlasher and select ESP32 Bus Expander (ESP32-C5, at least 4MB flash, no PSRAM needed).

Once it's done, you can connect the ESP32 Bus Expander (RX9/TX10) to the ESP32 Bus Pirate.
