Jalapeno power consumption

All power consumption tests are done with 8DEV_3001_Jalapeno_DVK. Both Gold (receiving) and DUT(transmitting).
Power measurement are done with UNI-T UT658 USB power meter.

Base power consumption, no wireless throughput

Work Mode	Power Consumption, W
module on, no ETH port plugged in, radios Down	2.2
1 ETH port plugged in	2.5
2 ETH port plugged in	2.7
2 ETH port plugged in, using as bridge and 1G throughput	3.1
2 ETH and 2G radio Up	3.2
2 ETH and 5G radio Up	3.5
2 ETH and 2+5G radios Up	4
Disabling USB	Module has no way to externally disable USB, disabling driver was not tried

Power consumption with wireless throughput, using different CPU clock frequencies

CPU	Rates	Throughput(5G+2G), Mbps	Temp(SoC/Radiator), C°	TCP/UDP	Voltage, V	Current, I	Power, W
718Mhz	Max	450+70	81/72	TCP	5.26	2.1	11
718Mhz	Max	600+100	83/74	UDP	5.26	2.3	12.1

Power consumption with wireless throughput, reducing transmit power

CPU	Tx Power, dBm	Throughput(5G+2G), Mbps	Temp(SoC/Radiator), C°	TCP/UDP	Voltage, V	Current, I	Power, W
200Mhz	5	40+60	72/64	TCP	5.26	1.1	5.7
200Mhz	5	200+70	73/65	UDP	5.26	1.3	6.7
200Mhz	10	50+61	72/65	TCP	5.26	1.2	6.2
200Mhz	10	200+71	73/66	UDP	5.26	1.3	6.8

Changing transmit power

iw dev <dev name> set txpower <limit/auto/fixed> <txpower in mBm>

<dev name>: device name, wlan0 for 2G radio, wlan1 for 5G radio
<txpower in mBm>: transmit power is set in mBm (mili Bell miliwat), mBm to dBm ratio is 100:1

CPU Frequency

To change CPU frequency

echo <frequency> > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo <frequency> > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

Available frequencies are: 200000 500000 718000

To see current CPU frequency

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Low power mode for RF power amplifier. Requires factory recalibration

Tx Power, dBm	Throughput(5G+2G), Mbps	TCP/UDP	Voltage, V	Current, I	Power, W
MAX -10	300+98	TCP	5.26	1.1	5.7

This mode sets the power amplifier to power save mode, reducing the output power by 10 dBm. This option requires factory recalibration to function properly.

CPU power consumption
