  • Bemerkung
  • The Malachite DSP SDR Receiver V5 is distributed by DeepElec shop in China, and it is one of many commercial and DIY projects based on the original Malahit DSP1 project owned by Malahiteam. A few firmware variants exists, however as the Malahit DSP1 is a proprietary project, new official releases must be acquired from Malahiteam.

    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).

    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.
