The DiP-Pi Power Master is an Advanced Powering System with embedded sensors interfaces that cover most of possible needs for application based on Raspberry Pi Pico. It can supply the system with up to 1.5 A @ 4.8 V delivered from 6-18 VDC on various powering schemes like Cars, Industrial plant etc., additionally to original micro-USB of the Raspberry Pi Pico. It supports LiPo or Li-Ion Battery with Automatic Charger as also automatic switching from cable powering to battery powering or reverse (UPS functionality) when cable powering lost. Extended Powering Source (EPR) is protected with PPTC Resettable fuse, Reverse Polarity, as also ESD.
The DiP-Pi Power Master contains Raspberry Pi Pico embedded RESET button as also ON/OFF Slide Switch that is acting on all powering sources (USB, EPR or Battery). User can monitor (via Raspberry Pi Pico A/D pins) battery level and EPR Level with PICO’s A/D converters. Both A/D inputs are bridged with 0402 resistors (0 OHM) therefore if for any reason user needs to use those Pico pins for their own application can be easy removed. The charger is automatically charging connected battery (if used) but in addition user can switch charger ON/OFF if their application needs it. DiP-Pi Power Master can be used for cable powered systems, but also for pure Battery Powered System with ON/OFF. Each powering source status is indicated by separate informative LEDs (VBUS, VSYS, VEPR, CHGR, V3V3).
User can use any capacity of LiPo or Li-Ion type; however, must take care to use PCB protected batteries with max discharge current allowed of 2 A. The embedded battery charger is set to charge battery with 240 mA current. This current is set by resistor so if user need more/less can himself to change it.
In Addition to all above features DiP-Pi Power Master is equipped with embedded 1-wire and DHT11/22 sensors interfaces. Combination of the extended powering, battery, and sensors interfaces make the DiP-Pi Power Master ideal for applications like data logger, plants monitoring, refrigerators monitoring etc.
DiP-Pi Power Master is supported with plenty of ready to use examples written in Micro Python or C/C++.

The Motorino board is an extension-board to control and use up to 16 PWM-controlled 5V-Servo-motors. The included clock generator ensures a very precise PWM signal and a very precise positioning. The board has 2 inputs for voltage from 4.8 V to 6 V which can be used for up to 11 A. With this input, a perfect power supply is always guaranteed and even bigger projects are no problem. The supply runs directly over the Motorino which provides a connection for voltage, ground and control. With the build in capacitor, the voltage is buffered which prevents a sudden voltage-drop at a high load. But there is also the possibility to connect another capacitor. The control and the programing can be done, as usual, with the Arduino. Manuals and code examples allows a quick introduction for beginners.

Add global GSM connectivity and GPS tracking to your project with a BerryGPS-GSM.
This is an all in one module which can provide location tracking and GSM services such as data, text and SMS to your project. It comes in the same form factor as a Raspberry Pi Zero, which makes it nice and compact when used with a Raspberry Pi Zero.
The two main components that make this board great are;
uBlox CAM-M8 GPS module (Same GPS found on BerryGPS-IMU V3)
uBlox SARA-U201 GSM for GSM connectivity, which has global coverage.
Both of these modules working together results in obtaining a GPS fix in secs, using Assisted GPS.
Typically, a GPS module can take a few minutes to get Time To First Fix(TTFF), or even longer if you are in built up areas. This is because the Almanac needs to be downloaded from satellites before a GPS fix can be acquired and only a small portion of the Almanac is sent in each GPS update.
Assisted GPS speeds this up significantly by downloading ephemeris, almanac, accurate time and satellite status over the network, resulting in faster TTTF, in a few seconds. This is very similar how to GPS works on a smartphone.
BerryGPS-GSM has been designed for the Raspberry Pi Zero, however it works with all versions of Raspberry Pi.
We have created a USB-to-USB PCB connector to be used with a Raspberry Pi Zero, which is designed to make your project more compact.

Maker Line is a line sensor with 5 x IR sensors array that is able to track line from 13 mm to 30 mm width.
The sensor calibration is also simplified. There is no need to adjust the potentiometer for each IR sensor. You just have to press the calibrate button for 2 seconds to enter calibration mode. Afterwards you need to sweep the sensors array across the line, press the button again and you are good to go.
The calibration data is saved in EEPROM and it will stay intact even if the sensor has been powered off. Thus, calibration only needs to be carried out once unless the sensor height, line color or background color has changed.
Maker Line also supports dual outputs: 5 x digital outputs for the state of each sensor independently, which is similar to conventional IR sensor, but you get the benefit of easy calibration, and also one analog output, where its voltage represents the line position. Analog output also offers higher resolution compared to individual digital outputs. This is especially useful when high accuracy is required while building a line following robot with PID control.
Features
Operating Voltage: DC 3.3 V and 5 V compatible (with reverse polarity protection)
Recommended Line Width: 13 mm to 30 mm
Selectable line color (light or dark)
Sensing Distance (Height): 4 mm to 40 mm (Vcc = 5 V, Black line on white surface)
Sensor Refresh Rate: 200 Hz
Easy calibration process
Dual Output Types: 5 x digital outputs represent each IR sensor state, 1 x analog output represents line position.
Support wide range of controllers such as Arduino, Raspberry Pi etc.

This module has an ultrasonic transmitter and an ultrasonic receiver so you can consider it as an ultrasonic transceiver. Familiar with sonar, when the 40 kHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be emitted back, and the receiver can receive the reflected ultrasonic wave. It is only necessary to calculate the time from the transmission to the reception, and then multiply the speed of the sound in the air (340 m/s) to calculate the distance from the sensor to the object. Features 3.3V / 5V compatible, wide voltage level: 3.2V~5.2V Only 3 pins are needed, save I/O resources Wide measurement range: 3cm ~ 350cm Plug and play with Grove connector Applications Distance measurement Ultrasonic detector Proximity alarm Smart car Technical Specifications Dimensions 50 mm x 25 mm x 16 mm Weight 17 g Battery Exclude Measuring range 3 cm - 350 cm Operating voltage DC 3.2 V ~ 5.2 V Operating current 8 mA Ultrasonic frequency 40 kHz Connector 1 x Grove Output PWM
