Gravity: I2C to Dual UART Module Shipping:4-6 Days SparkFun Pulse Oximeter and Heart

SparkFun Pulse Oximeter and Heart Rate Sensor

This is a wireless charging module based on “magnetic-coupled resonance” technology that only consumes one-millionth of the power of traditional electromagnetic induction power technology

both coils will always be on and limited to 100% of the current limit setting (unlike some other drivers that limit it to about 70% in full-step mode)

attention: DHT22 digital temperature and humidity sensor is designed for analog sensor interfaces

Gravity: I2C to Dual UART Module Shipping:4-6 Days SparkFun Pulse Oximeter and HeartThis I2C to Dual UART module offers data transmission rate up to 1Mbps, and each sub UART has independent 256 byte FIFO hardware buffer for transmitting and receiving. The baud rate, word length, and check format of every sub UART can be set independently. The module provides 2Mbps maximum communication rate. At most four such modules can be connected onto one controller board to expand 8 hardware serial ports. This I2C to dual UART module can be
