Figure 1: MMC Ready additional board
How to connect the board?
The MMC Ready additional board can be easily connected to a device or a microcontroller via pads CN1 and CN5.
Next to each pad, there is a designation indicating the microcontroller pin that it is connected to. The PICFlash external
programmer is used to program the microcontroller on the addititonal board. It is connected to the board via a 2x5
connector CN2, Figure 2.
How to use the board?
The program used to read SD memory cards is loaded into the microcontroller supplied on the additional board. If
needed, it is also possible to load another program into the microcontroller by using the PICFlash external programmer.
When the microcontroller is programmed, it is necessary to place jumpers over RB6 and RB7 pins on the CN2 connector.
Otherwise, pins RB6 and RB7 will not be connected to pads.

MMC Ready
The MMC Ready additional board is used to read and write to SD memory cards. It can also serve as a small development
system as it features a 28-pin microcontroller PIC18F252.
Key features:
- On-board microcontroller PIC18F252;
- External programmer is used for programming;
- Low power consumption;
- 5V DC power supply voltage.
