Matsushita® Bd-mlt Uj232as Firmware Update

Audio Interface Module RS232 - TTL


This circuit is only inteface RS232 to TTL, the aim is to use it to communicate with a microcontroller with the PC.

The idea of \u200b\u200bthis development is to build this interface in modular form to allow its use in the protoboard.Como is then the circuit was removed from its datasheet and the PCB was created as small as possible without using SMD integrated for ease in getting the components and assembly.

The PCB is as follows, in the following link can be downloaded in pdf ready for printing on transfer paper.

Here are some photos of the completed development.
