4tronix Picon Zero v1.3 - Intelligent Robotics Controller for Raspberry Pi
The Picon Zero is an add-on for the Raspberry Pi. It has the same size as a Raspberry Pi Zero, making it ideal to function as a pHat. Of course, it can be used on any other Raspberry Pi via a 40-pin GPIO connector.As well as two full H-Bridge motor drivers, the Picon Zero has several Input/Output pins giving you multiple configuration options. That allows you to easily add outputs or analog inputs to your Raspberry Pi without any complicated software or kernel-specific drivers. At the same time, it opens up 5 GPIO pins from the Raspberry Pi, and it provides the interface for an HC-SR04 ultrasonic distance sensor.The Picon Zero comes with all components, including the headers and screw terminals, fully soldered. Soldering isn't required. You can use it right out of the box.Features pHat format PCB: 65 mm x 30 mm Two full H-Bridge motor drivers. Drive up to 1.5 A continuously per channel, at 3 V - 11 V. Each motor output has both a 2-pin male header and a 2-pin screw terminal. The motors can be powered from the Picon Zero's 5 V or an external power source (3 V - 11 V). The Picon Zero's 5 V can be selected to be from the Raspberry Pi's 5 V line, or a USB connector on the Picon Zero. That means that you can effectively have 2 USB battery banks: one to power the servos and motors on the Picon Zero and the other to power the Pi. 4 Inputs that can accept up to 5 V. These inputs can be configured as follows: Digital inputs Analog inputs DS18B20 DHT11 6 Outputs that can drive 5 V and be configured as: Digital Output PWM Output Servo NeoPixel WS2812 All Inputs and Outputs use GVS 3-pin male headers. 4-pin female header that connects directly to an HC-SR04 ultrasonic distance sensor. 8-pin female header for Ground, 3.3 V, 5 V, and 5 GPIO signals allowing you to add their additional features. Hardware ConfigurationPicon Zero has two jumpers for setting the hardware configuration. Ensure that you have placed them in the correct position. JP1 – Board 5 V Selector. This jumper selects where to get the 5 V power from for the Picon Zero Outputs. The options are: Jumper at the top between RPI and 5 V. The 5 V power for the board is taken from the Raspberry Pi pins on the GPIO connector. Because of the low power output devices and the 5 V motors, all devices can be powered with a single 5 V power input. Jumper at the bottom between USB and 5 V. The 5 V power is taken from the microUSB connector on the Picon Zero. Useful for higher power output devices, since you can provide extra power through the micro-USB connector on the board JP2 – Motor Power Selector. This jumper selects where the motors get the power. The two options here are the following: Jumper at the top between MotorPower and Vin. The motors are driven via the 2-pin screw terminal. The voltage can be between 3 V and 11 V. Useful for motors that require a voltage different from 5 V, or that require more current than is available on either of the USB input connectors Jumper at the bottom between 5 V and MotorPower. The motors are driven from the board's 5 V. Raspberry Pi ConfigurationThe Picon Zero is an I²C device. Make sure your Raspberry Pi is set up correctly to use I²C and SMBus: sudo apt-get install python-smbus python3-smbus python-dev python3-dev sudo nano /boot/config.txt Add the following lines at the end of the file dtparam=i2c1=on dtparam=i2c_arm=on Press Ctrl-X and use the default prompts to save sudo reboot Plugin the Picon Zero onto the Pi and run i2cdetect -y 1If everything goes well, you will see the Picon Zero showing up as address 22 as shown below:

Sequent Microsystems Home Automation V4 8-Layer Stackable HAT for Raspberry Pi
The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485. The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs. A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state. Ideal solution for your Raspberry Pi Home Automation projects. Read temperatures in up to 8 zones with analog inputs. Control your heating and cooling system with the 8 onboard relays. Use the 8 optically isolated digital inputs for your security system. Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup. Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V). Control four light dimmers using 0-10 V outputs. Compatibility The card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user. Power Requirements The Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on. Relays The 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF. Stacking Multiple Cards Up to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level. Features Eight relays with status LEDs and and N.O contacts Eight layer stackable Eight 12-bit A/D inputs, 250 Hz sample rate Four 13-bit DAC outputs (0-10 V dimmers) Four PWM 24 V/4 A open-drain outputs Eight optically isolated digital inputs Contact closure/Event counters up to 500 Hz Four Quadrature Encoder inputs 26 GPIOs from Raspberry Pi available 1-WIRE and RS485 communication ports Pluggable Connectors 26-16 AWG for all ports On-board hardware watchdog On-board resettable fuse Reverse power supply protection Brass stand-offs, screws and nuts included Hardware self-test with loop-back cable Open source hardware, schematics available 32-bit Processor running at 64 MHz Uses only I²C port (address 0x28..0x2f ), all GPIO pins available Specifications Power supply: Pluggable Connector, 5 V/3 A Power consumption: 50 mA (all relays off), 700 mA (all relays on) On board resettable fuse: 3 A Open Drain outputs: maximum 3 A, 24 V Relays 1,2,3,4,5,8: N-O contacts, 6 A/24 VAC or DC Relays 6,7: 3 A/24 VAC or DC Analog Inputs: Maximum input voltage: 3 V Input Impedance: 50 KΩ Resolution: 12 bits Sample rate: 250 samples/sec.
