This MCU board also includes 4 UARTs (hardware serial ports)
Embedded Lwip and FreeRTOS
It decodes four binary weightedaddress inputs (A0 to A3) to sixteen mutually exclusive outputs (Y0 to Y15)
This ACS721 current module is based on ACS712 sensor
The chip accuracy of conversion is good and power consumption is also low to make it popular
Line Tracker Sensor 7-Segment Decoder This MCU board also includesIntroduction: TCRT5000 sensors continuously emit infrared infrared emitting diodes, infrared rays emitted when not being reflected back or reflected back but the strength is not big enough, the phototransistor has been in a shutdown state, then the output modules is high, indicating diode remains off state; when the object appeared to be detected within the detection range of the infrared is reflected back and the intensity is large enough, the
