This product by Ann Fuller electronic design and production to provide Chinese data, modules, schematics and routines (C51, AVR, STM8, STM32F4).
STM32-V5 Development board wiring method: directly socket interface NRF24L01 can.
Feature:
1, 3.3 V or 5.0 V DC Power Supply
2, MCU interface: SPI
3 main ADC chip: TM7705 (new chip factory in Shenzhen Tianwei, and AD7705 chip compatible)
4, the external LM285-2.5 reference voltage (imported genuine)
5 input circuit voltage divider resistor and RC filter, allowing customers to change their own gain range.
6, programmable amplifier chip with gain range: 1-128 times
7, the amplifier input buffer chip can be directly connected to the sensor.
Front: (actual delivery, 4P pin is not soldered, to facilitate the customer's choice of welding direction)
