  • DAB Color Slide show support (Data service option)
  • Decodes audio services up to 384kbps without external RAM
  • FM with RDS/RBDS decoder (*** RDS reception only available for station name, station text and genre and is subjected to certain condition of power level and frequency deviation)
  • Combined antenna input for FM / Band3
  • UART Serial control interface
  • Integrated stereo audio DAC
  • Digital audio output – I2S
  • Real time clock accurate 50ppm
  • Configurable general purpose I/O
  • Ultra low-power
The Microchip PIC18F14K50 provides a USB to Serial interface for the T4B module to communicate with the host PC. Despite the sample code provided in this Development Board for communicating with the board is based on serial communication, user can analyse the serial communication and implements a driverless HID protocol by rewriting the firmware on the PIC18F14K50.

New SlideShow Feature
The KeyStone T4B module supports SlideShow. Slideshow adds visual content (slides) to radio broadcasts on DAB or DAB+. It enhanced the digital radio with visuals using images in JPEG or PNG format.

What can you do with it?
  • Build a PC controlled DAB+ FM Digital Radio
  • Build a CAR PC DAB+ FM Digital Radio
  • Build a standalone DAB+ FM Digital Radio (requires external microcontroller)
HARDWARE DESCRIPTIONS
- Power Supply Circuit
The board is typically powered by 5VDC from USB. The PIC18F14K50 is drawing power directly from the USB-C port. From the USB’s 5VDC, the power is further distributed into 3.3VDC LDO to the KeyStone T4B module. The power of LDO is always on.

- Microchip PIC18F14K50
This microcontroller is used to provide a Virtual Serial Port to the KeyStone module. It is flashed with a customised CDC RS-232 Emulation Demo firmware. Other than performing the standard serial emulation, it also control the power, reset and audio shunt of the KeyStone module.

- Reset Circuit
Reset of the module is performed by RESET pin emulated by DTR of the virtual serial port.

- ICSP
The ICSP programming port is the standard Microchip’s In-Circuit Serial Programming port and is compatible with Microchip’s PICkit.

-EXT
EXT port has two 5V logic signals, ˉSHDN and ˉSHNT. They are used to control external audio circuitry’s power and mute.

- Push Button (SW1)
This button, when pressed during a power-up, will trigger the PIC18F14K50’s USB HID bootloader in programming mode.

Pre-installed Software
  • Microchip's USB bootloader (programming the board using a normal USB cable)
  • Microchip's CDC RS-232 emulation firmware

Packing List
  • 1 unit of DAB+ FM Digital Radio Development Board
  • 1 unit of retractable antenna

Great product, works perfect with API.
For use with RS232 only (no USB) you need to redesign the board and program the PIC.
The designer of the development board gives good support.

großartiger Support über Monkeyboard.org: technisch extrem kompetenter, freundlicher, schneller Support
sehr gute Doku
die Boards sind qualitativ top
- Empfang ist mit der mitgelieferten Antenne nicht so toll. Eine aktive wäre wohl als Nachrüstung sinnvoll.

di ottima fattura e funziona bene di contro ha l'attacco per una sola antenna che non riesce a prendere bene sia la banda fm che dab. Ho risolto con un commutatore di ingressi per le antenne manuale.
Altra cosa secondo me si potrebbe migliorare di molto facendo uscire l'audio in digitale.

Leider sind in dem Board nicht alle Features enabled, die der Chip bietet.

So funktionieren viele Funktionen, die in der Slave Mode Spec (V.3.4.1) beschrieben sind leider nicht.

Speziell die Funktion 7.2.51. Command 0x32: STREAM_GetRDSRawData
wäre interessant für den FM Betrieb um alle RDS Gruppen (TMC, TA,TP, AF, RD, RD ) auswerten zu können.

Sehr schade, hier sollte der Lieferant Monkeyboard dringend Abhilfe schaffen!! Er bestellt die Module lt. seinen Angaben nach seiner Spec.

Weiterhin sollte dem Modul ein HF Shield hinzugefügt werden. Ein Betrieb in der Nähe eines Rechners (hier ein Odroid XU4 mit Display) verhindert im FM Betrieb RDS.

Ebenso scheint der Hersteller des Empfängermodules Keystone nicht auf Anfragen zu reagieren. Mehrere Mails blieben bisher unbeantwortet.
Die Webseite http://www.keystonesemi.com ist auch auf dem Stand von 2012, was Fragen aufwirft.

Fazit: Für einen DAB/FM Receiver im Focus CarRadio mit TMC/TA/TP ist das Modul in seiner derzeitigen Form die falsche Wahl.

Sehr kompakt und dank Treibern und API leicht in eigene Lösungen zu integrieren (ich habe das Teil an einen Raspi gehängt und eine Anwendung dafür in C programmiert). DAB ist natürlich schon ein Argument gegenüber reinen UKW-Empfängern. Perfekt ist es aber nicht:

* Der DAB-Empfang ist mit der mitgelieferten Antenne mitunter hakelig. Ich habe eine aktive Antenne nehmen müssen.
* Es unterstützt kein Traffic Announcement (RDS-Flag, das Verkehrsnachrichten auszeichnet) und auch kein TMC / TPEG.
