Radix Nano NxT

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 docid\ cwfrveyggcdu25v63spki 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
