Raspberry Pi 3 with Wifi and Bluetooth on sale now for $35

Comments Off

The Raspberry Pi Foundation is not holding back. Since the original Raspberry Pi B launched four years ago, there has been a steady stream of new devices and upgrades: The much improved Raspberry Pi 2 came out two years ago, and it was just before Christmas that the tiny form-factor Pi Zero launched. Today, they’ve announced another upgrade in the form of Raspberry Pi 3 B, also selling for $35.

Apart from an upgrade to a 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU, the most exiting news is the integrated 802.11n wireless LAN and Bluetooth 4.1. Ideally, it means that no other external devices are needed, assuming that a Bluetooth keyboard works (sometimes they can be flaky).

This will likely be a hit, so expect to wait for some time for stocks to fill up with the different retailers. And of course, the stated price might not be obtainable if buying locally.

Looking at the 12 V stepper motor at SparkFun, I came across a few other fun links. Including instructions for stepper motor wiring, a DIY surveillance camera, and an example project for the Arudino, using an EasyDriver Stepper Motor Driver. Also interesting, were the hardware suppliers: here’s some clamping shaft couplers from ServoCity, and lots more from McMaster-Carr.

Finally, I was eyeing up on of the robotics kits at SparkFun: “The POP-BOT is an Arduino compatible, mobile robotic platform. It comes complete with wheels, motors, sensors, software, documentation, etc. The POP-168’s pin-out is similar to the Arduino Stamp“.
