Nano IO Shield

Preamble

This is a useful board that provides servo, XBee and nRFnRF24L01+ connectors for an Arduino Nano. It has onboard regulators for 5 V and 3.3 V. A external power supply of up to 12 V can be used, although, I would exercise caution if using a 12V PSU in conjunction with a Chinese cloned Nano, as 12 V at Vin could possibly cause the Nano to blow (12V + NANO VIN = SMOKE! help!). A 9 V 2 A PSU would be recommended. Continue reading Nano IO Shield

Using XBee 868 as R/C

Preamble

After having second thoughts about whether a XBee 868 is suitable for a RC, seeing as it is dubious if it is suitable for video transmission, see XBee and video streaming, I thought that it would be wise to check to see if they are appropriate for R/C control. This search surprisingly throw up some issues with the XBees devices, namely:

  • groundplane issues and;
  • packet freeze and the need to reset (due to a 10% duty cycle).
