4.3.1 Bill of materials
The following tables list the bill of materials. Table 2 details the parts common for all frequency bands,
Table 3 details the parts for the 915 MHz and 868 MHz frequency bands (default), Table 4 details the parts
for the 433 MHz frequency band, and Table 5 details the parts for the 315 MHz frequency band.
NOTE
The ANT1 component is designed to be used with 900 MHz and 800 MHz
frequencies, and the values for the components L3, C17, and C20 are
calculated for those frequencies and this particular chip antenna; in case
another antenna is required, those values must be readjusted according to
the new antenna and manufacturer recommendations.
