BEFORE STARTING: be sure to put your name on your kit box! Also be sure to
label your robot PCB with a marker pen. This will help get the items returned if they are lost or misplaced.
1 Printed Circuit Board Preliminaries
This section describes the initial steps to begin soldering the ECEbot’s circuit board. Look at both sides of the Printed Circuit Board (PCB). The front side has printed lines and labels called the “silk screen,” while the back side doesn’t have any printing on it. Notice that there are many
small labels on the front (silk screen) side of the board. The instructions will often refer to the components by these labels, like diode “LED3”, resistor “R11”, or header “J17”. Most of the
components will be inserted in the board from the front side by slipping the wires or legs through the drill holes, then soldering them to the back side.
