I tried to let the 'big brother' translate some of the chapters.īlock diagram on page 3 is quite informative:īlock diagram from the HR_C5000 datasheet

The datasheet for the HR_C5000 is mostly in Chinese. With the original firmware, during idle, with backlight off: circa 70 mAĢ.1 The C5000 'baseband chip' and its connections to the CPU Power consumption (measured directly at the battery terminals at 8 V): The complete schematicsĪlso some photos from the inside for the FCC registration.ĭMR transmit spectra measured before and hard- and software modification:Ĭompared with some other low-cost handheld transceivers, the TX spectrum is remarkably clean. That article also contains a part of the circuit diagram. To microcontroller nuts like myself: Don't miss Travis Goodspeed's 'Reverse Engineering the Tytera MD380' at

The keyboard and its connection to the CPU.

The display and its connection to the CPU.

Audio signal paths and the 'baseband' chip.

Measurements (transmit spectra, power consumption.

It will eventually make it into an additional 'hardware description',īesides the lots of details that you will find in the MD380 Tools already. At the moment, this document is just an unstructured collection of notes, started by DL4YHF.
