VERSION 1.2 M90, M100, M100
UART 2 (J15)
This is a TTL level (3.3V) UART 2 port of the TX1/2. The 2 pins are passed through a bi-directional level
converter with 3.3V level outputs (TXB0104PWR) and through 33 Ohm series resistors (in a tiny 0804 size
resistor array).
USB 2.0 (J17)
USB 2.0 port for firmware upgrades and for USB 2.0 devices like mouse and keyboard.
5V Power out (J23)
This is the 5V power out connector. It is the output of the on-board DC converter which is rated at 3A max. We
recommend not to source more than 1A per pin (connector limitation).
Optional Lithium battery (J60)
Optional MS621FE rechargeable battery to power the RTC of the TX1 or TX2 for extended times.
100BT (100Mbit) Ethernet (J7)
This port is only intended for very short Ethernet connections within a system. It features an RC network (and
not magnetics) for isolation. It is designed for small voltage differences between the M90 and the system it is
connected to.
