Description
The module can generate the following signals: sine, square and triangle with a frequency up to 3 MHz with an amplitude of 1 Vpp. The system communicates via the SPI bus. The board may also function as a shield onArduino Pro Mini.
MiniGen has two output connector: standard hole 2-pin connectorgoldpin raster 2.54 mm(not included in package, sold separately) and connector FL. The signal has an amplitude of Vcc/2 where Vcc is set by default to a value of approximately 3.3 V it gives the maximum value of 1 V.
|
The default module is set to the operation mode with a supply voltage of 3.3 V. This means that it is compatible withArduino Pro Mini 3.3 V version. To switch the voltage to 5 V, you need to solder the jumper on the back side of the board. |
|
The product is compatible with Arduino The manufacturer has preparedan Arduino libraryfor the module maintenance. Installation and connection facilitatesmanual available on-line. |
