Last February Raspberry released their second generation Raspberry Pi 2 Model B to replace the Raspberry Pi 1 Model B+. We have been testing our Raspberry Pi to Arduino shields connection bridge for the past weeks to be sure it is fully compatible with the new model.
Compared to the previous board its main features are:
- A 900MHz quad-core ARM Cortex-A7 CPU (6X Faster)
- 1GB RAM so you can run more powerful applications (512 Mb on the previous B+ board)
- Same board layout and footprint as the Model B+ (40 GPIO), so any board or shield designed for it should be compatible
- 4 x USB 2.0 sockets and MicroSD card socket for storage
Our Raspberry Pi to Arduino shields connection bridge
Our bridge board was developed to function as a link between Raspberry Pi and Arduino, making it possible to use any shield, board or module designed for Arduino in Raspberry Pi. With our bridge you can connect any analog or digital sensor using the Arduino pinout but taking full advantage of the new RaspberryPi 2 capabilities.
At the same time we created the arduPi library in order to use the Arduino code in Raspberry. We have implemented conversion functions so you can control any I/O interface the same way as in Arduino: analog, digital, i2C, SPI, UARTâ€¦ An updated version of this library is available here (compatible with Raspberry Pi 2).
It includes a socket so that you can connect any Arduino wireless module (XBee 802.15.4/XBee ZigBee, RFID, NFC, Bluetooth, Bluetooth Pro, WiFi). You can also connect any sensor with a precision of 16b through the integrated ADC or complex sensors through i2C and UART buses.
The new Raspberry is powered via microUSB socket (+5V @ 2A) so it can meet higher current requirements than its predecessor. For example GPRS and 3G shields occasionally demand high current peaks and this new board can provide them easily.
Testing our bridge with the new Raspberry Pi 2 model B
Since the layout of the new model remains unchanged, with 40 GPIO and all of the connectors in the same place with the same functionality, our shield connects with it perfectly. We have been testing every Raspberry Pi tutorial on our website to ensure every functionality works fine and haven't noticed any kind of problem so we are pretty happy with the outcome.
You can still use the same ARMv6 Raspbian on both Raspberry Pi 1 and 2, and because it has and ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10.
A real application of the bridge: use our e-Health sensor platform with Raspberry Pi
This connection bridge allows to use our e-Health sensor platform with Raspberry Pi. With the e-Health shield you can monitor up to ten different biometric and medical parameters and create applications where body monitoring is needed. The complete kit features ten different sensors: pulse, oxygen in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG), glucometer, galvanic skin response (GSR - sweating), blood pressure (sphygmomanometer), patient position (accelerometer) and muscle/eletromyography sensor (EMG).
