    Brief technical details

    The System Menu shows the SW version "RF805 V1.49.1"

    The PCB assembly reference is "L-528-DAB-V1.5   2022-5-5"

    The design is based around a GL3140A-B169 DAB/DAB+/DMB-A/FM RF, Baseband, Audio Processor, and MCU unit IC, by GL Glovane, and a ZB25VQ16ATIG 16Mbit Serial Flash IC, by Zbit Semiconductor, both mounted on a piggyback PCB marked as "RF805". The antenna signal is limited by one A7 dual-diode for ESD protecion.

    Two  PT3300-HS 3.2W Class D/AB Audio Power Amplifier IC's, by PTC, drives the two uilt-in 45 mm 4 Ohm speakers.

    A custom JCEB14F5B Bluetooth/Audio processor, by A3, handles several tasks like Bluetooth streaming, MP3 files decoding and audio stereo output for earphones.

    The power supply uses some additional active components to handle the battery charging (ME4084B Battery Linear Charger, by MicrOne, XB5608A One Cell Lithium-ion/Polymer Battery Protection, by Xysemi),  voltage regulation (S2UH and S3UC LDO regulators by Microne), and some transistors as switches (namely a AO3401-X15V P-MOSFET).

The EONKO model L-528DAB is also sold under the brand RADDY model RD33 for the European and American markets.

The only visible difference is the stick label at the back where the RADDY RD33 code is used instead of the original EONKO model L-528DAB code.

Below are pictures from Ralph T. and Uisge Beatha-Slàinte customers on Amazon Deutschland showing the back side of the cabinet:
