UI Board
UI board table of features:
| PCB Dimensions: | 186mm x 66mm |
| Processor: | STM32F76x (216 MHz Clock), optional STM32H743ZIT6 (400 MHz Clock, pin compatible with STM32F76x) |
| Audio Codec: | 2 x WM8731 @ 96KHz (UHSDR currently using 48 kHz only), separate IQ and Audio (TX and RX possible simultaneously, RF board needs to support this) |
| Display: | 3.5“ 480×320 as default, 3.2” and 2.8“ supported |
| LCD Interface: | parallel and SPI supported, parallel used as default |
| Internal memory: | SPI-Flash (Option), SPI-RAM (Option) |
| External memory: | microSD card |
| Realtime clock: | integrated Realtime Clock (RTC) part of STM32 MCU, CR2032 Backup Battery |
| LEDs: | 3 |
| External connections: | Mini-USB Type B, USB-Host (USB-A), 3.5mm connector for microphone and PTT, 3.5mm connector for analog input, 3.5mm connector for analog output (line-out is independant from loudspeaker), 3.5mm connector for headset |
| Internal connections: | 30pin connector (mcHF RF Board compatible), 6pin GPIO, 25pin connector (GPIOs, SPI, I2C), ST-Link V2 compatible Debug connector, Debug output, 2 x 4 Pin internal USB connections |
| Keys: | 18 separate keys |
| Rotary encoders: | 4 rotary encoders with integrated key function |
| Audio output: | Stereo, 2 x 3W at 2 x 4 Ohm with less than 1% THD+N |
The 30pin header J1 is downward compatible with the mcHF RF boards up to and including RF board V0.6. OVI40 UI and mcHF RF board can be used together. An improved OVI40 RF Board is in development.
