Raspberry Pi Model 4B
INPUT: 5V via USB-C, GPIO
GPIO: GPIO pins take 3.3V or less. 28 GPIO pins are available. Software PWM is available on all of them, and Hardware PWM is available on GPIO12, 13, 18, 19.
Python with GPIO: Use the GPIO Zero Library to interface with the GPIO pins with Python.
Use command [pinout] on GPIO Zero to get the pinout on screen.

Pi-Ez Connect Automation HAT
INPUT: Has separate 5V and 3.3V power buses. Each GPIO pin has at least two additional solder points.
PORTS: There are four 5V ports, four 3.3V ports, and 6 ground ports. There's a breadboard area in the middle of the HAT. There are also solder points for extra devices, as needed. The terminal blocks allow access to all GPIO pins.
FUSE: There's a resettable 8V/1.6A fuse that protects the 3.3V and 5V buses.
All terminals are labeled (G/P) for GPIO number and pin number.

Limit Switch
INPUT: Rated 380VAC/3A
Has NC, NO, and C ports. C is your output and NC/NO decide if it's default high or low. DON'T connect both NC and NO.
4
Pressure Sensor
(NSCDRRN001PDUNV)
PACKAGE: Dual Input Pin, Dual radial barbed ports, same side
PRESSURE: +/- 1 PSI differential. Working pressure is 5 psi. Over pressure is 10 psi. Burst pressure is 20 psi.
Input: Constant supply voltage needed: 1.5-12.0 Vdc above 6 kPa, 2.7-6.5 Vdc below 4 kPa. Accepts liquid media
Typical: 5V DC, 1.5A
Attach sensor with ports facing down if possible
Output: Unamplified, uncompensated. Normal offset: -2.5 mV/V. Analog.
PINOUT: With the ports facing upwards, the TOP-RIGHT port is port 1 and the BOTTOM-LEFT port is port 2. Counterclockwise from the top left, the pins are numbered 1-8.
Pin 1: GND
Pin 2: Vout+
Pin 3: Vsupply
Pin 4: Vout-
Pins 5-8: Not connected

4-Channel 16-Bit ADC for Raspberry Pi (ADS1115)
DATA RATE: Programmable between 8-860 SPS
SUPPLY: 3.3V and 5V from GPIO, 100mA momentary current and 10mA continuous current
I2C ADDRESSES:
0x48 (DEFAULT)
0x49
0x4A (If this one is used, we need to control SDA and SCL a little more carefully, so look into it/message me if you use this address)
0x4B
Output: You can configure the ADC to read absolute or differential voltage. Message me if you want to read differential voltage.
PINOUT (screw terminals):
With terminals facing UPWARDS, left to right:
5: GND
6: AIN0, Analog input 0
7: AIN1, Analog input 1
8: AIN2, Analog input 2
9: AIN3, Analog input 3
0: 3V3: 3.3V Output

Stepper Motor Controller
(TIC 36v4)
INPUT: 8-50V. 5V regulator.
OUTPUT: ~4A per phase without cooling.
Microstep resolution: from full, in powers of two down to 1/256
Supported interfaces: USB, TTL serial, I2C, Analog Voltage, Quadrature encoder, STEP/DIR inputs, RC servo pulses
Supports limit switch inputs with homing capabilities. Supports kill switch inputs.
PINOUT: Screw terminals, with micro-USB port UPWARDS:
