evive Technical Specifications
evive has its own inbuilt Li-ion 2200mAh battery, giving it portability and durability. It can also be powered externally by a USB wall charger, power bank, DC wall adapter, laptops and >12V batteries. These inputs have reverse polarity, overvoltage and overcurrent protection to protect you and your evive in the event of any mistakes. evive also has a host of power output ports, with a fixed 5V/3A supply, fixed 3.3V/0.8A supply and a tunable voltage supply from 1.25 – 30V/3A.

Direct outputs for running DC motors, stepper motors, pneumatics, relays and servos (for low current consuming hardware approx. 1A) make it as easy as plugging in your device into evive and directly playing with it using the hardware interaction module. For controlling high current consuming devices, it has 2 ports with signal outputs to control your motor drivers.

Pnuematics
evive has multi-modal feedback, both visual and auditory. The 1.8” TFT screen with 18-bit color and a resolution of 160x128px displays the menu which controls evive but can be programmed according to your custom needs. It has 1 single-color and 2 dual-color programmable LEDs, along with fixed LEDs for serial communication, power indication, and battery charging status. The auditory mode consists of a 2k-10kHz piezo buzzer.

Data Aquisition Module
evive has a particular data acquisition module, with 2 24-bit ADCs capable of voltage sensing (voltmeter) up to +/- 30V with 10mV accuracy, and current sensing (ammeter) up to +/- 3A with 3mA accuracy, at a maximum sensing frequency of 75 kHz. The onboard real-time clock can log data with timestamps, store it in an SD card, or transmit it via serial or Bluetooth.

SD Card Reader
evive can be used as a mini oscilloscope to visualize voltage and current measurements. It has lots of functions like scaling voltage level, time scaling to see the reading in a better way, trigger to start the measurement at some set value, scanning modes like single or continuous, offset, save readings to SD card and sending data to the computer.

evive offers a novel way of interacting with your hardware and code, via the menu interface displayed on the TFT screen and controlled using the 5-way switch. The pre-defined menu functionality includes driving motors and servos, data sensing and mini-oscilloscope, serial monitor, data logging, function generator, and pin states. Users can also add their own functions easily and access them through the user-defined functions submenu.
