OVI40 UI and mcHF RF board can be used together. An improved OVI40 RF Board is in development. Display Board Note: ToDo Photo Display size: 3.5 inch Display Type TN Resolution: 480 x 320 Controller: ILI9846 (and compatible) Human Interface: Touchscreen Interface: SPI and Parallel 2.8 inch oder 3.2 inch 320 x 240 Touchscreen Displays mit IL9325 (or compatible) controller can also be used. RF Board Note: ToDo Photo and Data table Housing Note: ToDo GHousing text and data OVI40 will not fit the current mcHF casings. In contrast to the mcHF, the OVI40 RF boards will have additional PCB boards plugged into them. It is assumed that these adapter boards may be up to 5 cm long. There will be OVI40 specific casings developped and provided who do not want to build their own housing. These housings will be developped after the OVI40 has been finished.
