    , max.: 3,6V , thereby delivering > 25 mA peak BlueMod+S50 is designed to be powered from 3V coin cell batteries e.g. CR2032 directly, or any other power source complying with the given requirements. For optimal performance, a stable supply is recommended. Furthermore, it is recommended to place a capacitor in parallel to the CR2032 3V coin cell battery to prolong battery lifetime, by compensating the effects of the rising source resistance of the battery to pulsed loads.
  • Page 14 BlueMod+S50 Hardware User Guide It is strongly recommended NOT to switch the module power supply on/off while other parts of the circuitry stay powered. This mostly leads to hardly controllable back-feeding issues. Due to the ultra-low power design a few µAmps are enough to raise VSUP to an undefined state, which may cause a hang-up deadlock if power is switched on again.
