Status LED: The status LED is the indicator of the two main 
status in which you can find the BITalino system, idle or 
acquisition. When you turn on the device the white LED will 
turn on for 3 seconds and then it starts blinking slowly. This 
means the system is currently in Idle mode and ready to 
start an acquisition, at which point the LED will blink faster.

 

 

  LED 2 

– Battery status LED: The BITalino Mini was 

designed to be a portable system and as such it is ready 
to be powered by a 3,7V battery using its onboard JST 
connector. The battery status LED was therefore added to 
advert the user of a low battery level. By default, the LED will turn on solid orange 
when the battery voltage reaches 3,4V. However, the firmware is ready to receive an 
order to adjust this threshold. Such can be easily accomplished via one the many

– Charging status LED: There is no need to use 

a third-party charger to charge the battery that powers 
the BITalino. The device presents an onboard charger 
that allows charging up the battery using a regular 
Micro USB charging cable. The charging status LED turns on solid orange when the 
device is charging, and it turns off once the battery is fully charged. 

 

2.5. UART & BLE 

By  default,  the  BITalino  Mini  uses  the  UART  protocol  to  send  information  to  the  onboard 
Bluetooth  Low  Energy  module  to  communicate  wirelessly  with  other  devices,  such  as  a
