Module size: 2.7cm x 4.4cm
The module adopts standard double panel with 1.6mm thickness, beautiful layout, with through holes around it, and the aperture is: 3mm, easy to fix.
Supply voltage: 5V
Module right interface:
GND: module power supply negative pole
VCC: module supply positive electrode;
CS: chip select signal input, active low.
RD: read the signal input, the low level output is effective.
WR: write signal input, low level start AD conversion.
INTR: the interrupt provider is completed after transformation. After the AD conversion ends, the low level indicates that the conversion has been completed.
D0-D7:8 bit data output port
Interface on the left side of module:
GND: module power supply negative pole
VCC: module supply positive electrode
The GND on the left and right sides are connected together, and the VCC on the left and right sides are also connected together. The two GND VCCs are for the convenience of power supply or for the use of other devices or modules.
Ain: analog voltage input interface
Test is the input of the test analog signal. After inserting the short-circuit cap, the analog signal input of the power supply is adjusted by the potentiometer on the board.
The board is made of high quality FR4-A fiberglass board. Every PCB board has passed the flying needle test before leaving the factory. It is a brand-new original component and the quality is dependable.
