This is essentially a ramped up version of Ardumoto motor driver shield. 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.
Features:
Voltage max: 16V
Maximum current rating: 30 A
Practical Continuous Current: 14 A
Current sensing available to analog pin
MOSFET on-resistance: 19 mΩ (per leg)
Maximum PWM frequency: 20 kHz

I. Overview 
The 5V ESP8266 four-way WIFI relay module uses the ESP-01 as a WIFI module, with a mature and stable 8-bit MCU chip. It can realize the wireless control of the 4-way relay using the mobile phone APP within the LAN in a simple configuration process. 
Second, functional characteristics 
1, Onboard high performance microprocessor and ESP-01 WIFI module; 
2, the module has 2 working modes: 
Mode 1: The mobile phone is directly mounted on the WIFI module; 
Mode 2: The mobile phone and WIFI module are loaded on the router at the same time; 
Additional features: It can also be used as a USB relay when the ESP-01 is unplugged.
3, transmission distance:
(1) In the open environment, the maximum stable transmission distance when the mobile phone is mounted on the WIFI module is 100m;
(2) When the WIFI module and the mobile phone are mounted on the router at the same time, the transmission distance is strong according to the signal of the router.
Weak and certain.
4. Use Smartconfig technology to complete the configuration of the ESP-01 WIFI module account and password on the mobile phone APP. The configured account and password have the power-off memory function.
5, On-board 12V, 10A/250V AC 10A/30V DC relay, can continuously suck 100,000 times, with diode escaping protection, short response time;

Description:This tiny little board does all of the neat-o for 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 -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.
Features:
ATMega 32U4 running at 5V/16MHz
Supported under for 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

Development board power supply
 
The following are the same as the "
CH340 chip supports 5V supply voltage or 3.3V supply voltage. When using 5V operating voltage, CH340 chip VCC pin input 5V power supply, and V3 pin should be an external capacity of 0.1uF power decoupling capacitor. When using 3.3V operating voltage, CH340 chip V3 pin should be connected with the VCC pin, while the external input 3.3V power supply, and with the CH340 chip connected to other circuits can not exceed the operating voltage of 3.3V.
Module defaults to 5V operating voltage, the chip voltage from the USB interface, if you want to change to 3.3V operating voltage, you need to back the module 5V, 3.3V working voltage selection point to switch to the middle point and another point shorted. At this point need to VCC feet to the module input 3.3V power supply, the module can work
