An updated ClusterHAT v2.6 will be available shortly.

The Cluster HAT is a simple way to connect up to 4 Raspberry Pi Zero to a host Raspberry Pi using USB Gadget network and serial with I2C power control via GPIO.

The main changes are:

* The USB HUB updated to the CH334F which has a Multiple Transaction Translator (MTT).
* The (now obsolete) XRA1200P I/O expander is replaced by an ATtiny1616 which ships with firmware emulating the XRA1200P. It also has a built-in UPDI programmer for the ATtiny1616 allowing simple updates or switching to custom/more advanced firmware.
