| + | "2 line bitmap LCD" Approximately 20 characters by 2 rows.\\ | ||
| + | IC1, 74VHC165 (8bit parallel line/serial out shift register) is used for serializing the keyswitch selections, | ||
| + | IC2. 74VHC595 (8-Bit Shift Register with Output Latches) is used for decoding serial data to latched outputs to turn on status LEDs (Power, Wifi, ADF) and one LCD control line (chip select)\\ | ||
| + | IC1 & IC2 can use power supplies of 2V to 5.5V, LCD 3.3V powered? | ||
