The Arduino–compatible VM800P ‘PLUS boards’ are based on the company’s FT800 EVE graphic controller devices, in which display, audio and touch functionality are all integrated onto a single chip. The boards also incorporate an 8-bit ATMEGA microcontroller unit (MCU) and a TFT display (with 3.5”, 4.3” and 5.0” inch sizes available). The 6 new daughter cards will allow the expansion of the boards’ I/O capabilities in order that they can be implemented into a wider range of application scenarios. They use 1 or 2 Micro-MaTch miniature connectors to interface with a VM800P.
The VI800A_TTLU is a plug-in accessory for the PLUS boards which enables inclusion of a TTL level UART. This daughter card behaves as an SPI-to-UART bridging mechanism. It is complemented by the VI800A_RELAY, which effectively acts as an SPI-to-relay bridge for PLUS boards, with the SPI slave interface converted into a relay interface. The VI800A-ETH allows an external Ethernet interface to be connected and the VI800A_PoE enables Power-over-Ethernet (PoE) functionality to be benefitted from. The VI800A N485U behaves as a SPI-to-RS485 bridge with the VI800A_232U behaving as an SPI-to-RS232 bridge – thereby allowing interfacing with legacy equipment.
“Our PLUS boards merge together the familiarity of Arduino and the technology of EVE, with its novel object-oriented approach to HMI implementation. Now, with the addition of these daughter cards, there are greater opportunities for more comprehensive external interfacing and a higher degree of control. This will unlock the true potential of EVE deployment in all manner of exciting new application environments,” says FTDI Chip’s Paul Huang.
The VI800A_TTLU, VI800A-ETH, VI800A_PoE, VI800A N485U and VI800A_232U each have a form factor of 63.50mm x 37.50mm, while the VI800A_RELAY has dimensions of 68.90mm x 48.75mm. The VM800P daughter cards will be priced from $24.95 for a single unit.
