Features:
WCS1800 Hall current sensor has two main functions.
The first function is analog signal followed by operational amplifier, which is suitable for A/D conversion.
The second function is the switching signal, which can set the current limit value in advance. When the actual current value is greater than the preset current value, the switching signal will change from low level to high level, and it will be indicated by an LED indicator.
Product parameters:
Working voltage: DC5V
Current detection range: DC: ±35A, AC: 25A (for analog output);
Linearity: K=60mV/A;
Current limit current range: 0.5A--35A (applicable to switch output);
Sampling current conversion analog voltage signal output, which can be connected to ADC, TTL level signal output, and can be connected to MCU IO port control.
The output signal is: analog voltage signal and switch signal
Indicator light: with over-current indicator
Interface Description:
VCC: power supply
DOUT: TTL high/low level signal output;
GND: power supply-
AOUT: sampling current signal conversion voltage output terminal
Instructions:
1. Instructions for use of analog voltage signal output (AOUT):
The relationship between the detection current and the analog signal output is as follows:
Analog signal output: V0=±la*K (the current actually flowing through the Ia current detection pin, K is linearity);
Taking the input current of 1A as an example, Vcc=5V, the linearity of WCS1800 is 60mV/A
Let's briefly talk about the corresponding relationship between WCS1800 detection current and output voltage when the current flows in from the positive direction:
The formula V0= la*K, corresponding output: V0=(2.5 0.06)V=2.56V
When current flows in the opposite direction:
The formula V0=- la*K, corresponding output: V0=(2.5-0.06)V=2.44V
If it is an AC signal: V0= la*K, the corresponding output range of V0: 2.44V-2.56V
The above is the ideal value, the actual value will have a small accuracy error.
2.Switch output (DOUT) instructions
If in a circuit, if the current is higher than 1A, the module is required to output a high level:
Step 1: Pass a wire of the detection end through the round hole of the sensor (note that the current flows in from the forward direction at this time), then turn on the power supply, adjust the current of the detection end to 1A, turn the adjustable resistor Vref counterclockwise, and turn it all the way. It is good when the red LED is on (the transition point when the LED turns from off to bright is good, don't screw it). At this time Vref>Vo.
Step 2: The setting of the upper limit current of 1A has been completed. Withdraw the 1A current, the LED will light up,
Step 3: In the future, when the current of the detected terminal exceeds 1A, the red LED does not light up, and the module DOUT outputs a high level at this time.

Description
For this monster shield we've replaced the L298 H-bridge with a pair of VNH2SP30 full-bridge motor drivers. We've also beefed up the support circuitry so this board is capable of driving a pair of high-current motors! The VIN and motor out are pitched for our 5mm screw terminals (not included), making it easy to connect larger gauge wires.
Note:When using this board in extreme high-demand applications it may be necessary to improve thermal performance with a heat-sink or fan and to solder the wires directly to the board instead of using a screw terminal (in addition to the myriad other complications present in a high-current system) However, when using the board at currents up to 6A the chips will barely become noticeably warm.

Description
This is the DC Motor Stepper FeatherWing which will let you use 2 x bi-polar stepper motors or 4 x brushed DC motorx (or 1 stepper and 2 DC motors).
Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and let the board take flight.
The original Adafruit Motor shield Kit is one of our most beloved kits, which is why we decided to squish it all together on a Feather Wing to make something even smaller, lighter, and more portable!
Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C.
Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based.
You can stack it with any other FeatherWing or with itself (just make sure you have each wing with a unique I2C address) Check out our range of Feather boards here.
Features:
4 full H-Bridges: the TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
Up to 4 bi-directional DC motors with individual 12-bit speed selection (about 0.02% resolution)
Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
Motors automatically disabled on power-up
Big 3.5mm terminal block connectors to easily hook up wires (18-26AWG) and power
Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
Completely stackable design: 5 address-select jumper pads means up to 32 stackable wings: that's 64 steppers or 128 DC motors.
