2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 I2C isolator click 2 3 4. Essential features Bidirectional isolators based on TIs Capacitive Isolation technology have many advantages over opto-couplers (performance, size, power consumption etc.). When used together with isolated power supplies, they block high volt- Turn the board upside down so that Turn the board upward again.
