Hardware Design
Amp'ed modules support UART, USB, SPI, GPIO hardware interfaces. Note that usage these interfaces dependant upon firmware that loaded into module, beyond scope this document. Notes unused pins should left floating; ground. pins must well grounded. area around module should free ground planes, power planes, trace routings, metal from antenna directions. Traces should routed underneath module. Module Reflow Installation BT-21 surface mount Bluetooth module supplied pin, 6-layer PCB. final assembly recommended reflow profiles are: Pb-free applications, Sn63Pb37 solder recommended. Maximum peak temperature 208° 210°C (below 220°C). Maximum rise fall slope after liquidous 2°C/second. Maximum rise fall slope after liquidous 2°C/second. Maximum time liquidous seconds. RoHS/Pb-free applications, Sn96.5/Ag3.0/Cu0.5 solder recommended. Maximum peak temperature 230° 240°C (below 250°C). Maximum rise fall slope after liquidous 2°C/second. Maximum rise fall slope after liquidous 3°C/second. Maximum time liquidous seconds.
