**Details** C103_Tibbit is a hybrid Tibbit hosting U-blox’s ZED-F9K, high precision automotive DR GNSS receiver. This Tibbit is going to be used with LTPP3-G2, Tibbo’s Linux-based Project Board. The Tibbit is capable of GNSS RF signal reception through an SMA connector; also, the TimePulse signal is exposed to the output world with RS232 (signal level) compatibility via a ubiquitous phone-jack. On the other hand, the CPU side of the Tibbit includes communication lines (UART and I2C) along with IO and interrupt signals; the original TimePulse signal of ZED-F9K is also exposed to the CPU side but with 3.3V level. In detail, C103_Tibbit consists of on-board configuration, test-points, antenna supervisory circuitry, level shifting, indicating LEDs for all CPU side signals and DC-DC converter for supplying the module’s power. This Tibbit is aimed to work in the industrial environment. If automotive certification is required, of course, the components selection can be changed. **Features** * H2T form factor * 4-5.5V input voltage range * 3.3V compatible I/Os on CPU side * Buffered signals between CPU and ZED-F9K * USB connector for firmware upgrade or standalone operation * Buffered and level-shifted TimePulse output(RS232 level) * Safeboot mode on-board configuration * Input/output overvoltage protection * Antenna control, short circuit/open circuit detection * Soft-start capability to avoid inrush currents * Temperature range: -40ᐤC to +85ᐤC * WEEE, RoHS, REACH and RED compliant
