I would like to use a Rabbit BL4S200 in a 12 V battery powered installation as part of a telemetry project.
Using DC function:
set_cpu_power_mode(10, CLKDOUBLER_OFF, SHORTCS_ON);
I only notice a very small reduction in current draw from the supply, 260mA down to approx 235mA.
Is it possible to reduce this further i.e. a sleep mode or would I have to look at using another model SBC optimised for low power modes such as the LP3500.
Any suggestions would be appreciated.
