Octopus Electronic Bricks, you can use them build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos even buttons, just plug and play.

BMP180 is a high precision, small volume and ultra-low power consumed pressure sensor used on mobile devices. It owns perfect performance with the lowest absolute accuracy of 0.03hPa. The power consumption is pretty low, only 3μA. BMP180 uses powerful 8-pin leadless ceramic chip carriers (LCCC) ultrathin package and connects various micro-processors directly via I2C circuit. Because its input voltage is 1.8V-3.3V, while generally the motherboard provides a voltage of 5V, we made a 5V-3.3V regulator circuit and 5V-3.3V level shifting circuit for the convenience of users.
