SF Innovations Custard Pi 2A Ready Built - Analogue & Digital Input Output Board for the Raspberry Pi (A, B, B+ & RPi 0, 2 & 3)

Description

The Custard Pi 2A is an analogue and digital Input/Output for the Raspberry Pi. This plug-in board provides digital outputs, 4 digital inputs, 2 analogue outputs, & 2 analogue inputs. The Custard Pi 2 provides the following benefits for the hobbyist intending to use the GPIO: 1. Provision of 4 open-collector digital outputs, 4 buffered digital inputs, 2 x 12 bit analogue outputs & 2 x 12 bit analogue inputs. 2. The board plugs into the 26 way or 40 pin GPIO connector (as appropriate to Raspberry Pi model in use). Two power on LEDs are fitted to the 3.3v and 5v rails to confirm correct plug in. 3. All the pins on the Pi are protected from accidental connection of a high voltage. 4. There are screw terminals provided for easy connection to external electronics: 4 digital outputs, 4 digital inputs, 2 analogue outputs, 2 analogue inputs and power. The GPIO allows the control of external electronics. There are 2 rows of 13 pins which are brought out to a 26 way header on the board. However, there are a number of points that a user has to take into account . There are 6 pins on this connector that nothing should be connected to. If anything is connected to these there is a risk of damage to the Raspberry Pi. All the pins work to 3.3v logic. Many electronic circuits work to 5v logic or even higher voltages. If a user accidentally connects a higher voltage to a 3.3v pin there is a risk of damage to Raspberry Pi. There are 2 voltage supplies provided on the GPIO, one at 3.3v and the other at 5v. However there is limited current availability from these pins and they are not protected from excessive current draw. Please note you are buying the Custard Pi 2A GPIO board, which does NOT include a Raspberry Pi itself.
