USB interface extension for Mimas V2 FPGA board

USB Interface Extension

This is a small board that uses MAX3453E chip to add a USB interface for an FPGA board. This extension is designed to fit into an extension connector on Numato Mimas V2 FPGA board, but it probably could be used with other boards that use 6x2 connectors (PMOD) or as a MAX3453E breakout board.

Connector Pinout

Pin	Function	Description
1	ENUM	Enumerate function select input
2	BD	Bus detection output
3	RCV	Differential receiver output
4	NC	No connection
5	V-	Negative receiver output/driver input
6	V+	Positive receiver output/driver input
7	SUS	Suspend input
8	#OE	Output enable
9, 10	GND	Ground
11, 12	VCC	Logic supply (1.65V to 3.6V)
