Part Lists for the NG Hardware 0.21

The following tables list the electronic parts needed to build the flight control, sensor board, breakout boards and some additional accessories.

You will probably get the best price by ordering your parts from CSD-Electronic and Reichelt Electronik. They are a bit slow sometimes, though. If you need something quickly you had better choose a different distributor.

What’s not available at CSD-Electronic, order from DigiKey or Farnell. That way you will get all the parts at around EURXXX at the time of writing.

Follow the bold mark to have only 4 distributors with the almost cheepest price including shipment. Problem may be Farnell because it delivers only to business customers.

Build Options

There are several options you can choose from.

Sum-Signal Option

Yout RC receiver’s PPM signal can either be handled by the main MCU (LPC2148) or the RC-Controller (ATmega644p).

Sum-Signal at the LPC (recommended)

• Populate R8, don’t populate R7, populate R17 and don’t populate R19

Sum-Signal at the RC controller (not yet functional)

• Populate R7, don’t populate R8, populate R17 and don’t populate R19

Buzzer Option

The piezo buzzer can either be connected to the 5V regulated supply voltage or directly to the battery supply (caution <!> ) :

Buzzer supplied from 5V (recommended)

• Populate R103, don’t populate R104

Buzzer supplied from battery voltage (only for some special buzzers)

• Populate R104, don’t populate R103

Never ever populate both R103 and R104 <!>

Voltage Regulator Option

You can choose between having a standard linear voltage regulator with attached heatsink or the more energy efficient and advanced switched voltage regulator option:

Switched Voltage Regulator (recommended)

• populate IC3 (PTH08080W)

Linear Voltage Regulator

• populate IC2 (7805 and heatsink)

Jumpers

There are several Jumpers that have to be set accordingly for correct operation of your NG.

SJ100

Connects pin 3 of the SB connector on the FC board with ground level. Set this jumper.

SJ101

This is a double jumper which allows you to choose the voltage level of the SSP interface and its slave select pins. Make sure you set it to any of both values. Additional hardware might someday require you to adjust this setting, but for now both values are just fine.

SJ102

Connects the output of the LiPo voltage measurement with pin AD0.4 of the LPC. The output is by default and unalterably also connected to pin ADC0 of the RC controller. The RC controller doesn’t measure the LiPo voltage at the moment which requires SJ102 to be set.

JP-U1 and JP-U2

Those jumpers let you choose the supply voltage of the UART connectors which might possibly power your USB/UART or RS232/UART converter. This will not change the actual voltage level of the UART.

JP-ISP

This is a double jumper which connects SDA1 or SDA0 with the nearby button. Setting a jumper and pressing the button at startup will either activate the UART (2-3) or USB (1-2) bootloader.

MLX Breakout Boards

This is the part list for the MLX break boards: every position three times

Note:: :: If you will use ADXR300/610 gyros you will not need the MLX breakout boards. The ADXR300/610 come with their own breakout boards!

LIS3LV02DQ Breakout Boards

This is the part list for the LIS3LV02DQ break board:

Tips & Tricks

• It seems to be a good idea to get a E12 Familypack of 0805 resistors and capacitors, it is much cheeper then getting all the resistors in single strips. For example, you can get them from CSD Electronics order number for resistor family pack is 10-08FAMPAK.
