 # USB Power Delivery for Arduino
 
-Implement a USB PD protocol analyzer, a USB PD trigger board or a more sophisticated power sink using a few additional components and simple Arduino code. Supports several STM32 microcontrollers.

-Depending on the microcontroller, a comparator and a few resistors are needed, or just the resistors or no additional component at all. See below for more details. For 5 USD in parts, you can build a USB PD protocol analyzer.
+Implement a USB PD trigger board or a more sophisticated power sink using simple Arduino code. Supports STM32 microcontrollers with UCPD peripheral and ESP32 microcontrollers with an external FUSB302 PD controller.
 
 
 
 ## Supported Boards
 
 | Board | Required additional components |
 | - | - |
-| Blue Pill (STM32F103C8) | Dual comparator, several resistors |
-| Black Pill (STM32F401CC) | Dual comparator, several resistors |
-| Nucleo-L432KC | Several resistors (for power sink) or none (for protocol analyzer) |
 | Nucleo-G071RB | None |
 | Nucleo-G431KB | None |
 | Nucleo-G474RE | None |
+| ESP32 | FUSB302 USB PD controller |
 
 All boards require an additional USB C connector as the standard connector is not ready for USB Power Delivery (no USB C connector, CC1/CC2 signals not available, voltage regular cannot handle more than 5V).
 For the Nucelo boards in Nucleo-64 form factor, the X-NUCLEO-SNK1M1 shield can be used.

 ## Examples
 
-### Protocol Analyzer
-
-The protocol analyzer can be connected between two USB PD devices to monitor the USB PD communication.
-
-```c++
-#include "USBPowerDelivery.h"
-
-void setup() {
-  Serial.begin(115200);
-  PowerController.startMonitor();
-}
-
-void loop() {
-  PDProtocolAnalyzer.poll();
-}
-```
-
-See the Wiki for details regarding the required components and wiring.
-
-
-
 ### Trigger Board
 
 The trigger boards communicates with a USB power supply and requests a different voltage than the initial 5V.
