Radix Nano NxT

4 min

The Radix Nano NxT is the next generation of PIC Development Boards where the focus is the Application, not necessarily the device in use.

Power Supply

The Radix PCBs can be powered by either the USB port or through the DC Power header.

When using the Nano with the USB port, the PCB is powered directly from the device powering the PCB. The nominal USB voltage is ~5v0.

When using the DC Header, the input voltage should not exceed 7v0, and the LD1117 a low drop-out regulator will regulate the voltage at ~5v0. The regulator is rated for 850mA which is sufficient for most applications.

External modules for example a GSM modem may require an instantaneous current of approximately 2 Amperes. If such a module is used, ensure that an additional external DC power supply is available.

Device Programming

The device is programmed using the integrated ICSP header. The device is flashed with a hex file generated by a compiler using a PICKIT programmer.

Bootloading the device is possible, see the following section: Programming the Device

USB UART

The USB UART enables the Nano to be connected directly to a desktop PC and the USB comms are converted to be compatible with the RS232 or UART Peripheral.

Headers

All headers are tracked from the edge of the PCB to the device, and the PINS are individually labeled for easy identification.
