+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]].
-[[hardware:start|...more]]
 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.

 We also included a 4-pin 3.5 mm **audio connector** which allows both (mono) headphone and microphone operation with a standard headset.
-There are two micro USB ports, both can charge the battery. USB0 can be used for software updates and data I/O to SDR software like GnuRadio.
