SquareWear LED Badge Kit

This is a DIY kit (requires soldering) to make your own LED badge and use it with SquareWear! The board measures 2″x2″ (5cmx5cm) and is fits 3mm LEDs. The kit comes with one PCB, 50 LEDs at your choice of color, and two alligator cables.

To use it, design a pixel pattern you like, such as a smiley, a heart, or a letter etc. Then insert LEDs to the corresponding pins. The longer (positive) lead of the LED should go into the pin marked ‘+‘. Half-grid points are allowed, as long as the longer lead goes into a ‘+’ pin. All LEDs are connected in parallel, so they will all light up together. You can fit a SquareWear behind this board (using double sided tape and appropriate insulation) to make a standalone LED badge. The board has sewable pin holes on the four corners. To control it with SquareWear, connect the + sewable pin to SquareWear’s Vdd, and - sewable pin to one of the power sink pins.

Here are some example patterns to get you started:

Special LEDs (pack of 5)

These are special LEDs that will bring a lot of fun to your projects! Each comes in a pack of 5.

• Self-Flashing Red: connect it to a battery and it will starting flashing on its own at 1Hz.
• Self-Flashing/Fading Multi-Color: has built-in three color LEDs, will flashes and fades at a pre-configured pattern.

Click on the embedded movies on the left to see these LEDs in action.

AASaver LED Kit v1.1

This is the updated AASaver v1.1. Includes one assembled and tested circuit board, four AA battery clips, two bright white LEDs (25000 mcd), and two 2-pin headers. This version can be used as both breadboard power supply and LED flashlight, through an on-board switch.

DS1307 RTC Module (with battery)

DS1307 real-time clock (RTC) module with built-in lithium rechargeable battery, 4KB EEPROM, 1×4 pin headers, and female jumper wires. Suitable for previous versions of OpenSprinkler that do not have built-in RTC. You can also use this module with standard Arduino or other microcontroller projects. To use, just connect the SCL, SDA, VCC and GND pins to the corresponding pins on your controller (note that VCC must be connected to the +5V/VIN line on your controller; connecting it to 3.3V will NOT work).

USB Programmer (DIY kit) for OpenSprinkler v1.0/1.1

This is a DIY USBtiny programmer for OpenSprinkler v1.0/1.1, which allows you upload a .hex program larger than 30KB. It comes handy if you have OpenSprinkler v1.0 or 1.1, and want to reflash the controller with firmware v1.8 or above. The kit includes everything you need to build the programmer (soldering required).

Note: if you own a separate OpenSprinkler DIY kit of v1.2u or above, you do not need this programmer, because you can use the built-in USBtiny programmer on v1.2u or above to program your v1.1 or 1.0 mcu.

USB-to-Serial (RS232) Converter

This is an integrated USB-to-Serial (RS232) converter based on Prolific PL2303HX chip. A low-cost and convenient tool for debugging and serial communication. Compatible with Adafruit’s same product.

• Cable length: 3 feet (1 meter).
• Wiring: Red->+5V supply, Black->Ground, Green->TX, White->RX. Connect TX to the RXD pin of your target device (such as microcontroller), RX to the your device’s TXD, and ground to ground. Usually you do not need to connect the +5V supply pin, as long as your target device is powered.
• No driver needed on Linux. Windows and Mac drivers can be downloaded here. The device will report as a Serial COM port. You can then use Arduino’s serial monitor, putty, gtkterm, or any of your favorite serial monitors to talk to it.

OpenSprinkler v1.2u PCB

This is an undocumented version of OpenSprinkler 1.2u PCB.
Schematic and board design can be found here. The part list is very similar to the official OpenSprinkler 1.2u. The main difference is that this version uses LM2574N switching regulator (same with OpenSprinkler v1.1). These PCBs are provided as is — we do not have build instructions, which you can figure out from the official 1.2u and 1.1 instructions. Besides OpenSprinkler, you can also use this PCB to build a general Ethernet and RF12 enabled Arduino board. The pin connections are compatible with JeeNode and NaNode.
