How to build your … Orangepip Segments328 To put your Orangepip Segments328 together you will need basic soldering skills. When soldering you should always work on a flat surface in a well-ventilated environment. Make sure you have plenty of room on your workspace. Equipment you will need … Soldering Iron Solder Side Cutters Snipe nose pliers Multimeter Assembly aid/ helping hand Check your kit before starting, to make sure you are not missing any components.
1.0 Locate the bag containing the resistors. This will include 5 pieces in total. Sort them carefully into their respective values using the illustrations below. There are three ways to identify the value of a resistor: 330R x 2 pieces. Orange, Orange, Black, Black, Brown 1 Using a Multimeter • Polarity doesn’t matter to the measurement. • It removes the possibility of misreading one of the resistor colour bands. • It can be a quick way to check when you have multiple resistors. 1K x 2 Pieces.
2.0 Locate the crystal and place into the board. Use the leg bending tip from earlier to keep the crystal flush to the PCB and solder in place. 2.1 Locate the bag containing the microcontroller and the DIL socket. The chip carrier socket is not polarity sensitive, but you will notice that there is a notch in one end. This is used to assist with the correct placement of the Microcontroller, which is polarity sensitive.
2.3 Separate the ceramic capacitors from the other components. The 0.1uF capacitors are marked with the number 104 and the 22pF are marked with the number 22. 5x 0.1uF 2x 22pF 2.4 Place the 0.1uF (104) capacitors into the marked locations on the PCB and solder in place. 2.5 Place the 22pF (22) capacitors into the marked locations on the PCB and solder in place. 2.6 Locate the 7805 voltage regulator (L7805CV).
2.7 In the image on the right you can see that the component has been laid flat against the PCB to offer a lower profile. This can be done with a pair of needle nose pliers or by pushing the component into the board and applying pressure to flatten the device. If you have any doubts about doing this, the product can be soldered upright with no negative effects other than an increased height profile. If you decide to do this then we recommend saving it until last. 2.8 Next, the tactile switch.
2.10 Locate the PTC resettable fuse. This component is not polarity sensitive so place into the PCB and solder in place. 2.11 Locate the 47uF electrolytic capacitors. These are polarity sensitive, so you need to ensure they are mounted the correct way round. To assist with this the capacitors have two indicators to help identify the orientation. The first is that the positive (anode) leg is longer than the negative (cathode).
3.1 Locate the ICSP 6 pin header. This is not polarity sensitive, but you will notice that the legs either side of the black plastic are different lengths. The shorter ends should be on the underside of the boards with the longer ends accessible from the top. 3.2 Locate the green and red LEDs. The LEDs are polarity sensitive and need to be inserted into the PCB the correct way round. We can use a similar method to the electrolytic capacitors to determine the correct orientation.
3.4 Locate the 2.1mm DC socket. Insert it into the PCB and solder in place. 3.5 The last job is to insert the ATmega328 microcontroller into the chip carrier socket you soldered earlier. The microcontroller is polarity sensitive. Find the end that has the notch and line this up with the notch on the microcontroller. Place the microcontroller gently into the socket. Ensure that the pins are lined up with those of the socket and apply firm but even pressure to seat the microcontroller in the socket.
