The A20-Linova1-7 HMI, also called Q027_2_F which is printed on production
label, is an industrial Human Machine Interface.
It features:
- 512MB DDR RAM
- 1 Sd-card >= 4GB
- 1 Usb otg(programmable via software) with A-Usb Connector
- 1 Usb host
- 1 Buzzer
- 1 Input for LiPo
- 1 Relay to signal absence of power supply
- 1 External Rtc with 56 bytes of ram + CR2032 battery
- 1 7" 24-bits Tft 800x480 with PCap on
- 1 Mono audio 1-watt amplifier
- 1 RS485 port
- 1 Power On Line through +12Vdc reaching 57.600baud,
from where it can be supplied and placed in a network of 50 units
- exposed jtag pins
HMI is supplied from +12Vdc.
Ethernet is absent, so for debugging, need to enable rndis on Usb otg
port through an A-A usb cable.
It comes in different flavours for connector types and can be found with
umounted features as requested by customers.
