Hardware development based on IEEE 802.15.4

• Mote 2,4 GHz
  

  The ZigBitAmp mote is a smaller version of the Meshnetics mote that is mainly based on the module ZigBitAmp, ZDM-A1281-PN Atmel. This is a module 2.4GHz 802.15.4 / ZigBee RF amplifier.

• Mote 868/915 MHz
  

  The ZigBit900 mote is a smaller version of the Meshnetics mote version and consists mainly of a ZigBitAmp MNZB-900-B0 Atmel module, that it is a module of 868MHz, 915MHz. We have included an RF amplifier.

• Solar Panel
  

  This circuit is for charging a lithium battery (1230mAh, 3.7V 4.5Wh) using solar panels. The load process is done by the integrated MAX1811. It has the following features: Accuracy of 0.5%, an output diode to indicate the charging status (in our case it is not used for optimization of consumption). Selectable charging current (100mA or 500mA), and it is valid to two types of batteries (4,1V and 4.2V). It has an Enable input pin thus we can manage the load process with the mote. The voltage of the solar panels is constant and not exceed 5V. The controller used is L7805. We use the solar panel SOLAREX MSX 005F, 0.5W.
