Extension Module

Extension Module

This is a module for connecting to the HMD Radio Socket additional components using the Antilatency Hardware Extension Interface. Using it, you can read the external triggers of buttons or connect additional circuits to the Socket.
Use a USB Type-C cable to connect the Extension Module to the power supply.
There are 8 pins available for the connection, each of them can operate in input or output mode. Any 2 of the pins can be set to pulse the counting mode simultaneously. And only 4 among the pins - to PWM mode.
Please note, analog and VBUS pins are located symmetrically on both sides of the board.

The maximum voltage on all pins is 3V.
IOA3 and IOA4 are low-speed pins. The signal frequency should not exceed 10kHz.
The current consumption from the pin in Output mode must not exceed 4mA.
Input - an input mode with internal pull-up (≈13 kOhm). The state of the pin is updated every 5ms, and if it has changed, it is sent to the Host.
Output - an push-pull output mode.
PulseCounter - a floating input mode used to count the number of rising edges of the signal. With it, you can connect other circuits e.g. a capacitive sensor circuit.
PWM - a push-pull PWM mode that outputs a PWM signal of a given duty cycle and frequency. With it, you can control the brightness of the LED or of the intensity of vibration. Also, you can use it for connecting circuits or as analog output using a RC filter.
Analog - an analog input mode with a 10 bit resolution.
