September is in full swing. New York Maker Faire is happening this weekend and the Hackaday Superconference is right around the corner. It also means that it’s time to poke around on the Tindie Flea Market and see what’s going on!
BatteryDuino Battery Shield for Arduino Uno
If you ask how to power an Arduino, there are many correct answers. However, if you want an easy way to do so, this battery shield looks perfect. Simply plug it into the pin on your Uno, insert 3 AAA batteries, and you’re good to go!
DRV8825 Stepper Driver Modules (2 Pack)
Steppers, while more controllable than DC motors, take a bit more finesse to get working. If you’re in need of a stepper driver board, these DRV8825 modules can drive 2.5A per coil, and feature better performance than more common A4988 drivers.
RTC Breakout
Dev boards like the Arduino Uno work well for many purposes, if you want to keep accurate time over more than a few hours, you’ll want to add a separate real-time clock (RTC) module. This device breaks out a DS1307 RTC chip, and includes a coin-cell battery holder and crystal.
5.4 Amp Stepper Motors
So do you need a few steppers to go with the driver listed above? If so, then these three… might not be appropriate given their 5.4 amp rating. Still, at 20 bucks for the lot, they could be a good find for the right project!
