RADIX - NANO 28

lead in the radix nano 28 caters specifically to the 28 pin devices these devices are available in various packages and are ideally suited to single purpose applications or monitoring a specific element while a small pin package type device, the architecture of these devices is sophisticated, enabling them to be used in a wide variety of modern applications for example iot side by side shown above are the two line art diagrams showing the two versions of the pcb they are identical offering the same features, except that the "b" variant is for the dip packages using the b variant enables you to swap out the device when purchasing the radix nano b, select the correct device or the nano 28 b will be supplied with no device 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 lead out the radix nano 28 a or b offers a versatile and practical pic development board to enhance the development capabilities for your project include additional modules, sensors, or other external peripherals
