Serial control interface   RoHS compliant SlideShow EPG (hardware support, software under development) The Microchip PIC18F14K50 provides a USB to Serial interface for the T2_L4A_8650C 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 With an upgrade module using the KeyStone T2_L4A_8650C, this board now support 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.     Board Dimension 78mm x 45mm What can you do with it?

The power of these three LDO is controlled by the SHDN pin.   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.       Packing List   1 unit of DAB+ FM Digital Radio Development Board Pro with KeyStone T2_L4A_8650C 1 unit of retractable antenna   Pre-installed Software Microchip's USB bootloader (programming the board using a normal USB cable) Microchip's CDC RS-232 emulation firmware **Product Type:** physical ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkCi0lJIghwdXIGOwBUSSIMYmxvYl9pZAY7AEY=--8353cd604c1965db49460d254c1c4da1a6f4f2f6/image_c6ae8427-362a-4b42-9002-2b4b52c7ef89.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
