Voltage detection module DC 0-25V Voltage Sensor detector
SKU:
2197
In stock
TThis module is based on principle of resistive voltage divider design,
can make the red terminal connector input voltage to 5 times smaller.Arduino analog input voltages up to 5 v,
the voltage detection module input voltage not greater than 5Vx5=25V
(if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).
Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023),
so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.

SOP-8 ATMEL AT93C56A AT93C56 93C56 SOP8 IC/SMD EEPROM
SKU:
2157
In stock
The AT93C56 provides 2048 bits of serial electrically erasable programmable read-only memory (EEPROM), organized as 128 words of 16 bits
each (when the ORG pin is connected to VCC), and 128 words of 8 bits each
(when the ORG pin is tied to ground). The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are
essential. The AT93C56 is available in space-saving 8-lead PDIP, 8-lead
JEDEC SOIC, 8-lead EIAJ SOIC, 8-lead MAP, 8-lead TSSOP, and 8-lead dBGA2
packages.
