  Brief technical details

  The RF Tuner is divided in three sections, each one shielded by metal covers.The section 1 contains the Front-end LNA, attenuator and some pre-selector filters and RF switches. The section 2 contains the remaining pre-selector filters and RF switches. The section 3 contains the MSi001 RF Tuner chip by MIRICS (U15) and the NAU88C22 Audio CODEC and Speaker Driver chip (U1).

  A STM32H743-VIT6-V 480MHz, 32-bit ARM Cortex-M7, 1MByte Flash,, 512KByte RAM chip (U5) and a RS256B/FM25W256 32KByte F-RAM (U17) manages the radio.

  The power supply and control circuitry uses several active devices, namely a TP4056 battery charger (U20), four LDO regulator chips (U3, U32, U19, U23), and several transistors.
