FTDI Basic Breakout USBTTL 6PIN 5V Module Fio/Pro/RGB/Lilypad Program Downloader for Arduino MWC MultiWii Mini USB (T1 downloader lilypad)
Features:
This is the newest revision of our FTDI BASIC. It now uses a SMD 6-pin header on the bottom, which makes it smaller and more compact. Functionality has remained the same.

This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work for Arduino and cloned for 5V for Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable.  This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any for Arduino board that has the reset pin brought out to a 6-pin connector.

The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with for Arduino target.

This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.

This board was designed to decrease the cost of for Arduino development and increase ease of use (the auto-reset feature rocks!). For Arduino Pro boards and For LilyPads use this type of connector.

LilyPad Buzzer module (T1 wearable buzzer)

 This is a small buzzer for the LilyPad system. Use 2 I/O pins on the LilyPad main board and create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.

Please note: This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to low (0V) when the buzzer is not used. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers.

DC 5V WCS1800 Hall Current Detection Sensor Module 35A Precise With Overcurrent Signal LED (2A2 WCS1800 Hall Current)
Description:

The WCS1800 Hall Current sensor has two functions

  • current detection
  • over current protection (can be preset from 0.5A to 35.0A)

Features:

Operating voltage: DC 5V
Current detection range: DC +-35A, AC 25A
Linearity: K=60mV/A
Limit current range: 0.5A to 35A(for on/off value output)
Over current signal indicator LED
Sampling current conversion analog voltage signal output and it can connect ADC; TTL level signal output and it can connect MCU IO port control
Board size 37mm x 31mm
Working temperature: 25 to 85C

Interface



VCC: power positive
DOUT: TLL high/low level signal output
GND: power negative
AOUT: sampling current signal conversion voltage output port

Analog voltage signal output (AOUT)

Relationship between detection current and analog signal output is shown below:

Analog signal output: V0=Vcc*0.5±la*K (la is actual current through current detection pin, and K is linearity)

Eg: Input currentis 1A, Vcc=5V and WS1800 linearity is 60mV/A
  1. When the current flows in from positive direction: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
  2. When the current flows in from negative direction: V0=Vcc*0.5-la*K, V0=(2.5-0.06)V=2.44V
  3. If it is an AC signal: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V

The above are ideal values. There might be some precision errors.

On/Off output(DOUT)

  1. Make sure the current flows in from the positive direction. Adjust to the desired current warning level.
  2. LED will be on when current is below the setting and DOUT will be low.
  3. When the detected current is higher than your setting, the LED will turn off and the DOUT pin will go high.

Package Includes:

1 x WCS1800 Hall current detection sensor

Electro-Fashion, LED Flasher Module Kit (T1 LED Flasher Module Kit)
Product Description

This unit provides a simple way of adding flashing white LEDs to a textiles project using conductive thread. The unit is programmed with a number of flashing patterns, which are selected by a push button on the main board. Pressing this button cycles through the following patterns: all LEDs constantly on, slow flash all on all off, fast flash each in turn and turned off. The device features auto-off, which turns the unit off after 30 minutes to preserve battery life.

This kit is supplied pre-built so requires no soldering. Each kit comprises three small PCBs. The largest of the three PCBs holds an LED plus the control electronics, battery and a push button. On both of the remaining PCBs there is an LED, these are connected to the main board with conductive thread (supplied).
