 ===== Battery =====

-The battery we use is of the type LiPo (Lithium-Polymer). They are currently the most popular battery type for R/C use. The LiPo is hoverer not the safest chemistry and should be handled with care. Failing to do so could make it catch on fire. It is also sensitive to under/over charge, to high discharge/shortage, heat and more. What it is good at however compensates for all these shortcomings as it has among the best power to weight ratios and discharge currents.

 ===== Expansion header =====

-The expansion header is located on the left side of the Crazyflie. It is a 10x2 pin 1.27mm (0.05") pitch trough-hole footprint which comes unmounted. The idea with the through-hole is that it makes it possible to mount expansion boards on either or both sides. It would even be possible to stack several on top of each other.

 The header is divided into two parts. The JTAG part, pin 1 to 10, and the buss/power part, pin 11 to 20. The UART RX/TX is located on the JTAG part because on many FTDI based JTAGs it is possible to use one channel for serial communication which can be very handy when debugging.
