The USB-MIO (Universal Serial Bus – Multi Input Output) is an I/O interface board for USB. The I/O board has 40 physical I/O ports that can be configured and used in different ways. The cirquit board has expansion and configuration pin-headers, IC sockets and some through-hole components that makes it easy to modify and adapt the hardware for different needs.
Hardware features:
- 36 digital inputs
- 35 digital outputs
- 12 high-current push-pull digital outputs (5...18V and up to 1A per output)
- 2 PWM inputs
- 2 PWM outputs
- RS-232 interface with RxD, TxD and two additional I/O's for RTS/DTR and CTS/DSR
- 8 analog inputs (10-bit ADC)
- Adjustable voltage reference for ADC
- On-board 7805 voltage regulator
- I/O ports ESD protected
Firmware features:
- Get and set value(s) of digital I/O port(s)
- Input and output clocked pulse trains on digital I/O port (separate clock and data pin)
- Read value(s) from analog input(s)
- Measure PWM signals
- Generate PWM signals
- Read temperature from DS1820 1-wire sensor
- LCD interface (HD44780 compatible)
- Autonomously execute PLC like program (host PC not needed)

Inga större missar i layouten. Några komponenter kom onödigt nära varandra, och några hål-kondensatorer kunde bytas mot SMD:
Kortet är designat för att passa i en standard box, efter att man fräst ner kanterna var skruvplintarna och de andra kontakterna kommer ut. "Frontpanelen" är ett riktigt klistermärke i plast:
Bra pris också...
