8. ADC Self-correction Function
AO-1505/AO-1505A has built-in a set of 12-bit high precision analog / digital converter
(ADC). This ADC input voltage range is between 0V and 3.3V. If the voltage beyond the rated
input range, it will cause permanent damage to the module. Due to different batch of wafer, ADC
characteristics will be slightly different. Hence, the AO-1505/AO-1505A module has built-in
self-correction program. Users only need to provide three 100K precision resistors (refer to circuit
application R2, R3, and R4) outside the series as a reference voltage source in order to get accurate
voltage output data. Refer to Section 5.3 AO-1505 response analog input status for the voltage
output format.
9. Antenna Characteristics and Installation Notes
To ensure optimum Tx/Rx efficiency for the antenna, users of the AO-1505/AO-1505A should
follow the following notes:
Don’t encapsulate the AO-1505 module in a metallic box. This does not apply to the
