The PWRshield module is a programmable LVD(Low Voltage Disconnect) and HVD(High Voltage Disconnect) power protect system. Programmable voltage setting for LVD and HVD(rocker switch set to AUTO). With emergency ON or OFF function, if you want switch output to be immediate and remain ON or OFF, you can set rocker switch to ON or OFF. | Design based on microcontroller and low loss MOSFETs (on status resistance < 0.002 ohm), you do not have to add heatsinks even for 30 Amps of continuous working current. | Standard 30 Amps power pole connectors. High quality aluminum enclosure, thickness 1.5mm/0.06". | Package includes: 1x PWRshield module, 2x black power pole housings, 2x red power pole housings, 2x PVC cover flame retardant sleeve, 4x silver plated copper 30A 14-12AWG power pole contacts. | Datasheet: https://m.media-amazon.com/images/I/91dFIuxkQ1L.pdf

Working voltage DC 0 to 32V. Maximum total input current 30 Amps. 6 Channels output, each channel maximum output current 3 Amps (Factory-installed fuse value 3 Amps, you can replace the fuse to support up to 10 Amps.) | Input terminals pitch 7.62mm/0.3", maximum current 30 Amps for per position, wire size 26~10 AWG, stripping length 8mm, Metric M3 slotted screw. Support power supply expansion connect to other modules. | Output terminals pitch 5.0mm/0.197", wire size 26~12 AWG, stripping length 7mm, Metric M2.5 slotted screw. | Fuse holders for Medium Blade ATO/ATC Fuse, the fuse can be removed and replaced very easily. With fuse fail indication function, when you connected load and the fuse has blown or has been unplugged, fail indication LED will turn on. | FR-4 fiberglass dual copper layers PCB. High quality Taiwan DINKLE fireproof nylon material DIN rail mount carrier (not China low quality carrier), can support width 35mm rail.

Taiwan High quality fireproof nylon material mount carrier(not China low quality carrier). Also included two M3 x 10mm wood screws, you can easily mount it on a wooden board.

Reversing relay module. Powers any reversing motor equipment, can be used for any application that requires the ability to reverse motion | Support Momentary-action(Self-resetting) switch and Alternate-action (Self-holding) switch. For Self-resetting switch, when the switch is pressed the motor operates, and when the switch is released the motor stops. | Compact plastic case and wires connect for easy mount. | Forward and Reverse status indicating LED, forward status lighting red, reverse lighting green. When the control switch is not turned on, the module does not consume electric energy. | Rated current 10 Amp, Operating Voltage: 20 ~ 30V DC.

The item has been soldered and assembled. Support for Raspberry Pi 1 Model B+, Pi 2 Model B, Pi 3 Model B, Pi 3 Model B+, Pi 4 Model B, Pi Zero, Pi Zero-W, Zero-2W. | GPIO status LED and power 5V / 3.3V indication. GPIO output or input level high LED on, output or input level low LED off. 5V blue, 3.3V red, GPIOs green. The position of the LED is in a one-to-one correspondence with the position of the Raspberry Pi 2x20pin connector, and the logic level of the GPIO can be observed very quickly and intuitively. The driving current of each LED is only 0.1mA, so you don't have to worry about it affecting the read and write status of GPIO. | Terminal block pitch 2.54mm/0.1", wire size range 28AWG to 18AWG, strip length 4.5mm, screw M1.6 steel, pin header and cage copper. | 2x20 positions header connect to Raspberry Pi board. FR-4 fiber glass PCB, dual copper layers. | Packing list: 1x terminal block breakout module, 4x M2.5x6mm screws, 4x 10mm nylon standoffs. 2x 11.5mm brass standoffs, 1x small slotted screwdriver (NOTE: the item not include Raspberry Pi Board).
