The CT800 features an ARM Cortex M4 microcontroller of an Olimex H405 board [1] that operates up to 168 Mhz, with 1 MiB of flash memory, 192+4 kiB of SRAM, and multiple I/O and USB connectors, with a 4x20 character text display, two leds, and a 4x4 + 1 keypad as peripherals aka user interface. Voltage source is due to four NiMH rechargeable AA batteries or external 5 V DC power supply.
