Description
CJMCU-8232 sensor module
Single-lead heart rate monitoring front end
AD8232 is an integrated front end, which is suitable for signalling cardiac bioelectrical signals.
No. conditioning for heart rate monitoring.
An integrated signal conditioning module for ECG and other bioelectric measurement applications. The device is designed to extract, amplify and filter weak bioelectric signals in the presence of noise caused by movement or remote electrode placement. This design enables an ultra-low power analog-to-digital converter (ADC) or embedded microcontroller to easily collect the output signal.
AD8232 uses a two-pole high-pass filter to eliminate motion artifacts and electrode half-cell potential. The filter is tightly coupled with the instrumentation amplifier structure, which can realize single-stage high-gain and high-pass filtering, thereby saving space and cost.
AD8232 uses an unused constrained operational amplifier to create a three-pole low-pass filter, eliminating additional noise. The user can select the cutoff frequency of all filters to meet the needs of different types of applications.
In order to improve the common-mode rejection performance of the system line frequency and other undesirable interferences, the AD8232 has a built-in amplifier for driven lead applications such as right-side drive (RLD).
The AD8232 includes a fast recovery function, which can reduce the long set-up tail of the high-pass filter. If there is a sudden change in the amplifier rail voltage (such as a lead-off situation), the AD8232 will automatically adjust to a higher filter cut-off state. This function allows the AD8232 to achieve rapid recovery, so that a valid measurement value can be obtained as soon as possible after the lead is connected to the electrode of the measurement object.
The rated temperature range for guaranteed performance is 0 ℃ to 70 ℃, and the operating temperature range is -40 ℃ to 85 ℃.
application
Fitness and exercise heart rate monitoring
Portable ECG
Remote health monitoring

2 IN The positive input terminal of the instrumentation amplifier. IN is usually connected to the left arm (LA) electrode.
3 −IN The negative input terminal of the instrumentation amplifier. −IN is usually connected to the right arm (RA) electrode.
4 RLDFB Right leg drive feedback input terminal. RLDFB is the feedback pin of the right leg drive circuit.
5 RLD Right leg drive output terminal. The drive electrode (usually the right leg) should be connected to the RLD pin.

Description
This is a breakout board for Freescale's MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs.
There a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin to 10k pull-up resistors. If you don't require the pull-up resistors you can open the jumpers by cutting the trace connecting them.
There is no regulation on the board, so the voltage supplied should be between 2.5 and 3.6VDC. The VREG pin is connected through a 0.1uF capacitor to ground, which means, unless you modify the board, you can't operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).
Size:3cm x 2cm .

Description
The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board. The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface.
This tiny little board does all of the neat-o For arduino tricks that you're familiar with: 4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 16MHz and 5V, this board will remind you a lot of your other favorite For Arduino-compatible boards but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 12VDC. If you're supplying unregulated power to the board, be sure to connect to the "RAW" pin on not VCC.
This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled. We've also added a PTC fuse and diode protection to the power circuit and corrected the RX and TX LED circuit.
Dimensions:1.3x0.7"
Features:
ATMega 32U4 running at 5V/16MHz
Supported under Arduino IDE v1.0.1
On-Board micro-USB connector for programming
4 x 10-bit ADC pins
12 x Digital I/Os (5 are PWM capable)
Rx and Tx Hardware Serial Connections
Our Smallest For arduino-Compatible Board Yet!
