Does anyone know if the Smakn Beetle has any interrupt pins?
I bought a few of these on Amazon (https://www.amazon.com/dp/B011AYAOHS), claiming they were Leonardo compatible (minus a few pins), and so far I'm finding they're ok little boards. Unfortunately, there's virtually no documentation on them.
I'm trying to hook one up to an MPU-6050 IMU, and the sketch requires at least one interrupt pin. Even though it uses the same chip as the Leonardo, and so should have external interrupts on digital pins 0, 1, 2, 3, and 7, none of those seem to be present.
The silk screen only indicates it exposes digital pins 9, 10 and 11, and analog pins 0, 1, and 2.
It also exposes Tx and Rx, and on the Uno/Leonardo, Rx corresponds to the digital 0 pin, which is also interrupt 2.
Is it safe for me to assume this is also an interrupt on the Beetle?
