| + | a) No antenna, only deco, pads for additional RGB LEDs (see [[:leds|RGB LEDs]])\\ | ||
| + | b) more pads for RGB LEDs (in total there are 3 RGB LED areas, on the part that looks like an antenna, and in the lower left and right area of the board) (see [[:leds|RGB LEDs]])\\ | ||
| + | c) **On/Off-Switch**\\ | ||
| + | d) **Micro-USB (A) for connecting to laptop**\\ | ||
| + | e) Micro-USB (B) for additional energy (limited to 475 mA)\\ | ||
| + | f) external clock out, an SMA connector (X201) could be soldered here (not for antennas!)\\ | ||
| + | g) clock generator, for sophisticated applications you may want to cover this with a metallic shielding to prevent irradiations (see [[extension:rfkit| extension:rfkit]])\\ | ||
| + | h) on-board PCB antenna\\ | ||
| + | i) pads for SMA connector (X301) or external antenna. Any edge-launch SMA socket for 1.6mm PCB thickness should work. (see [[:antennas|Antennas]], note the warnings for soldering!)\\ | ||
| + | j) radio frequency part, for sophisticated applications you may want to cover this with a metallic shielding to prevent irradiations (see [[extension:rfkit| extension:rfkit]])\\ | ||

| The rad1o badge contains a full-featured SDR (software defined radio) half-duplex transceiver, operating in a **frequency range of about 50 MHz - 4000 MHz**, and is software compatible to the [[https://greatscottgadgets.com/hackrf/|HackRF]]. | The rad1o badge contains a full-featured SDR (software defined radio) half-duplex transceiver, operating in a **frequency range of about 50 MHz - 4000 MHz**, and is software compatible to the [[https://greatscottgadgets.com/hackrf/|HackRF]]. | ||

| It is based on a Wimax transceiver which sends I/Q samples in the range of 2.3 to 2.7 GHz to an ARM Cortex M4 CPU. The CPU can **process the data standalone** for various applications (like FM receiving, spectrogram display, RF controlled power outlets, etc.), **or pass the samples to a computer** using USB 2.0 where further signal processing can be done e.g. using [[http://gnuradio.org/|GNU Radio]]. Radio signal transmission is also possible in standalone mode by software running on the ARM CPU, or from samples that are sent to rad1o through USB. | It is based on a Wimax transceiver which sends I/Q samples in the range of 2.3 to 2.7 GHz to an ARM Cortex M4 CPU.
