This new version adds 2 standoff holes as well as an extra decoupling capacitor. The ADXL345 is a small, thin, low power, 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to -16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited to measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0 degrees;.

The cable is easiest way ever to connect to your microcontroller/Raspberry Pi/WiFi router serial console port. Inside the big USB plug is a USB<->Serial conversion chip and at the end of the 36" cable are four wire - red power, black ground, white RX into USB port, and green TX out of the USB port. The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chip-sets.

This is an IC Test Clip for 8-pin small outline integrated circuits (SOIC). This test clip assures a secure connection to all chip leads on an 8-pin SMD SOIC and provides hands-free testing. On this test clip you will find two sets of gold plated contacts, upper contacts to attach wiring and lower contacts for an 8-pin IC. Simply place your choice of IC in the lower contacts and attach female terminated jumper wires to the 0.1" spaced upper contacts and you are ready to start testing!
