Power consumption of candidate hardware solutions

Components, i.e., incomplete solutions

0.24W - 0.45W FTDI cable + RFD900 (TX @ 100mW) with link but no traffic 0.048A - 0.09A @ 4.995V
0.33W - 0.50W CP210x cable + RFD900 (TX @ 100mW) with link but no traffic 0.066A - 0.1A @ 4.995V
0.50W - 0.55W TP-LINK WR703N (idle, no USB hub, memory stick, USB serial adaptor or RFD900 radio) 0.099A - 0.110A @ 4.995V
0.19W - 0.60W FTDI cable + RFD900 (TX @ 250mW) with link but no traffic 0.037A - 0.12A @ 4.995V (but peaks are likely reduced due to sampling issues in our test environment).
0.70W - 0.73W Mesh Potato 2 (idle, serval mesh not installed, no RFD900 attached, WiFi running AP+ad-hoc, no USB) Data from Steve Song based on current draw from power supply.
0.84W - 0.88W MK808B (idle, Wi-Fi client mode, HDMI display disconnected, Serval Mesh not installed, FTDI serial adapter plugged in, no RFD900 attached): averaging 0.168A - 0.175A @ 4.995V
0.45W - 0.90W Mesh Potato 2 (idle, serval mesh not installed, no RFD900 attached, WiFi running AP+ad-hoc, no USB) Our data, but where the average sits is hard to know. Steve's data is better in that regard: 50mA - 100mA @ 9V, 41mA - 71mA @ 15V
0.96W - 1.05W TP-LINK WR703N (idle, Wi-Fi in simulatenous ad-hoc & AP mode, USB hub, memory stick, running servald, no USB serial adaptor or RFD900 radio) 0.191A - 0.21A @ 4.995V
1.05W - 1.25W MK808B (idle, Wi-Fi client mode, HDMI display disconnected, Serval Mesh not installed, FTDI serial adapter plugged in, RFD900 attached (TX @ 100mW), link but no traffic) averaging 0.210A - 0.25A (but jumping around wildly in that range) @ 4.995V
1.00W - 1.50W MK802ii (idle, HDMI display disconnected, Serval Mesh not installed) 0.20A - 0.30A @ 4.995V
1.05W - 1.50W MK802ii (idle, HDMI display connected, Serval Mesh not installed) 0.21A - 0.30A @ 4.995V
