VNH2SP30 Stepper Motor Driver Module 30A

VNH2SP30 Stepper Motor Driver Module 30A

A perfect VNH2SP30 Stepper Motor Driver Module 30A for your needs

Description:

This is essentially a ramped-up version of the Ardumoto motor driver shield. For this 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.

Feature:

Voltage max: 16V
Maximum current rating: 30 A
Practical Continuous Current: 14 A
Current sensing available to Arduino analog pin
MOSFET on-resistance: 19 m (per leg)
Maximum PWM frequency: 20 kHz
Thermal Shutdown
Undervoltage and Overvoltage shutdown

Package include:

1 x VNH2SP30 Stepper Motor Driver Module 30A

Humidity and Temperature DHT11 Module

Humidity and Temperature DHT11 Module

This is a very popular, ultra low cost digital temperature and humidity sensor. It uses a capacitive humidity sensor, and a thermistor to measure the surrounding air temperature. The result is available via a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds. But, for most applications this is not an issue at all.

Specifications

Power supply voltage: 3.3~5.5V DC
Output: the single bus digital signal
Measuring range: 20-90%RH humidity, temperature 0~50°
The measurement accuracy of +-5%RH: humidity, temperature +-2 °
Resolution: 1%RH humidity, temperature 1 °
Exchangeability: fully interchangeable,
Long term stability: < ± 1%RH/
