Get your retro on with the Raspberry Pi compatible SNES style USB gamepad! This is not an official Nintendo product, but a 3rd party USB type replica of the Super Nintendo/Famicom unit produced in the early 90's!

We tested quite a few from different suppliers, and these were the best - with nice snappy, clicky buttons, and the traditional blue, red, green, yellow layout.

Features:

• USB Connector
• Raspberry Pi Compatible
• D-Pad
• Buttons: Start, Select, X, Y, A, B, R, L
• Cable Length: 1.4m

• Voltage: DC12V
• Current Draw: DC12V/60mA
• Fail Secure: Locked when power off
• Extension length: 9.8mm close
• Lock Size: 53 x 39 x 25(mm)
• Bolt Dimension: 9.8 x 9(mm)
• Weight: 150g

In between bouts of hacking and tinkering every Raspberry Pi programmer needs some rest and recreation! What better way to relax and unwind, than loading up your favourite 90's retro game and blasting some aliens pew pew!

These Raspberry Pi gamepads not only look the bee's knee's, but they have a comfortable rubber edging, have excellent tactile #clicky# feedback and work with all the emulators we could get our hands on! It's wired USB with a 1.4m cable, and it's plug and play with RetroPie.

Note: the central 'Mode' button does not work with some emulators.

Button-wire, it features all the usual suspects - A,B,X,Y,R1,R2,R3,L1,L2,L3, START, SELECT, and D-PAD. It's also got additional analogue joysticks which are mapped to the D-PAD; you turn them on and off with the big shiny red button in the middle. Honestly, what more do you need from a gamepad?

Note: This gamepad has been tested for the Raspberry Pi however we cannot guarantee it will work with other systems such as Windows.

  • totally 4 channel H-bridge, with 600mA output current (peak 1.2A) per single bridge
  • ESD protection

What's on Board

1. External power supply jack
2. Power input/output pinheader
3. Stepping motor interface
4. DC motor interface
5. M_PWR configuration : connects M_PWR (motor power) to 5V or ADJ
6. Power selection switch
7. Power indicator
8. AMS1117-ADJ : onboard linear regulator with adjustable output
9. Adjustable potentiometer : for adjusting the output voltage of ADJ (adjustable motor power)
10. L293D : dual H-bridge driver
11. LM2596-5.0 : onboard linear switching regulator with 5V output

Note : when in operation, it's normal that the onboard motor drivers and regulators generate lots of heat.

Description:

The MAX7219 are compact, serial input/output common-cathode display drivers that interface microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit. Only one external resistor is required to set the segment current for all LEDs.

Sonoff Dual is a WiFi based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means 1 Sonoff Dual control switch equals to 2 Sonoff basic switches! Sonoff Dual 2 gang light switch inherits Sonoff Basic switch’s advantages such as easy installation and operation, quick WiFi access, remote control through APP EweLink.

In the application eWeLink, available on both iOS and Android, users can independently turn on/off each of the two connected devices. But the button on Sonoff Dual 2 gang WiFi light switch is not an ON/OFF toggle switch, it is only a WiFi pairing button. Users can set single/repeat/countdown timing schedules to turn on/off at a specified time, and also share with others so that they can control together.

Works With Amazon Alexa

You can ask Alexa to turn on/off Sonoff Dual.

Standard voice control commands phrases for Sonoff Dual (if you just say the device name, Alexa will turn on/off all the 2 gangs immediately):

Alexa, turn on {deviceName}
Alexa, turn off {deviceName}

Alexa, turn on {deviceName} {gangName}
Alexa, turn off {deviceName} {gangName}

Explanation: if the device name of your Sonoff Dual is "My Switch", the gang name is "Gang 1", then you can control with "Alexa, turn on My Switch Gang 1".

To check compatibility of a new remote with the receiver. Simply press the button on the remote, if the receiver flashes, but does not Triger the relay. The remote will be compatible, and you can start the programing process

To add a remote, press the button on receiver momentarily. The red light will come on. Then press the button on the remote that you want to program in. The red light will start flashing. After 4 flashes in will stop, and the button will be programmed in.

For the setting to take effect, the board needs to be disconnected from it’s power supply. The bellow settings will be done to the 3 headers and bridge pin on the receiver board, above the push button.

• With the header removed, the On button will switch the relay on, and the off button will in turn switch the relay off.
• With the header on Pin 1-2. Both Buttons will become momentary. And only hold the relay in place as long as they are pressed in.
• With the header on Pin 2-3. Each button will be able to switch the relay on and off individually. You will however not be able to switch the button off with the “off” button, if you switched it on with the “on” button. And vise versa.

Package Includes:

1 x Learning Code Receiver Relay
1 x Remote Control

Description:

Game On! These wireless games controllers are perfect for all of your Raspberry Pi gaming or robotics needs.

Please note: These are not Bluetooth controllers - they're 2.4GHz wireless (and come with the USB receiver).

Gaming

Compatible with RetroPie/Lakka - simply plug in the controller at boot and follow the controller setup instructions.

You may need to configure buttons for the specific emulator/game you're playing. The RetroPie/Lakka websites and forums are a great place to find out more on button assignments.

For analogue control, make sure you press the analogue button on the controller to enable full analogue thumbstick action (otherwise this is seen as simple button clicks)

Robotics

Control your Raspberry Pi robots with ease! We've got instructions for using these controllers with the CamJam EduKit 3 (although other driver boards and kit will work too)

You can also use the excellent Approximate Engineering Input library!

Install the library by using the following commands:

sudo apt-get install python-dev python-pip gcc

pip3 install approxeng.input

Please run your script with Python 3 when using this library! (Python 2 may not work).

Features

• Tested with the Raspberry Pi
• Compatible with other systems such as Windows (however not all games/software will work with all types of controllers)
