 In my testing a 38KHz demodulator worked with 36KHz and 40KHz remotes, but this
 is obviously neither guaranteed nor optimal.
 
+The TSOP4838 can run from 3.3V or 5V supplies. The former should be used on
+non-5V compliant hosts such as ESP32 and Raspberry Pi Pico and is fine on 5V
+compliant hosts too.

 The pin used to connect the decoder chip to the target is arbitrary. The test
-program assumes pin X3 on the Pyboard, pin 23 on ESP32 and pin 13 on ESP8266.
-On the WeMos D1 Mini the equivalent pin is D7.
+program `acquire.py` uses the following pins by default:
