User manual
Figure 8
shows the schematic of the NXQ1TXH5DB1355 board. It contains an LDO to
create the 3.3 V supply voltage for the LPC824 microcontroller and the pull-up resistor of
2
the I
C connection.
Header X4 exposes a UART connection to the FTDI cable to connect to the PC.
Header X5 and header X3 contain the I
transmitter with the NXQ1TXH5.
