Olimex has recently featured a new board named VGA2HDMI It is a VGA to HDMI converter board that can take in VGA signals and convert them into HDMI signals. The reason it’s news is because one search will give you many HDMI to VGA converted and not the other way around.
The company announced this board because their old boards like the CERBERUS 2100, AgonLight 2, and Agon Origins boards all use A VGA connection as output and as that standard is getting obsolete the company specially designed and tested this convert to work with the old board.
Olimex is not the first company to design a VGA to HDMI converter; a quick search on Amazon search will reveal many such devices. However, the Olimex converter stands out as an excellent choice. It is competitively priced and is open-sourced, which means you can access schematics and KiCad source files directly on its product page. Additionally, more information and resources are available on its GitHub page under the reciprocal GNU General Public License 3.
The Olimex VGA to HDMI converter, built around the CV8986 IC, supports 1080p video and 24-bit audio ADC, potentially allowing audio transmission over HDMI when properly designed. The datasheet confirms these capabilities, alongside features like HDCP 1.3 and CEC 1.3 support. Curiously, it lacks a 3.5 mm audio jack. This 56-pin IC measures 7mm x 7mm, operates from -30 to 85 degrees Celsius, and includes a 32-bit Cortex M0+ core.
The company also provides an enclosed for the Board but that costs a little bit more than the original product.
Olimex VGA2HDMI Converter Specification:
- Chipav CV8986 VGA to HDMI converter
- VGA connector
- HDMI connector
- USB-C power connector
- Dimensions – 55 x 31 mm
The Olimex VGA2HDMI board, compatible with any VGA and HDMI interfaces, is now on sale. It is priced at €15 to €17 (about $16 to $18.50) and is available through the Olimex store with an optional plastic case.
