(phone) 408 213-9530 ( fax ) 408 213-9533 hardware design amp?ed rf modules support uart, usb, spi, and gpio hardware interfaces. this section details typical usage models for these features. please note that the usage of these interfaces is dependant upon the firmware that is loaded into the module, and is beyond the scope of this document. notes ? all unused pins should be left floating; do not ground. ? all gnd pins must be well grounded. ? the area around the module should be free of any ground planes, power planes, trace routings, or metal for at least 8 mm from the antenna in all directions. ? traces should not be routed underneath the module. module reflow installation the bt-21 is a surface mount bluetooth module suppli ed on a 24 pin, 6-layer pcb. the final assembly recommended reflow profiles are: for non pb-free applications, sn63pb37 solder is recommended. ? maximum peak temperature of 208 - 210c (below 220c). ? maximum rise and fall slope after liquidous of < 2c/second. ? maximum rise and fall slope after liquidous of < 2c/second. ? maximum time at liquidous of 50 ? 90 seconds. for rohs/pb-free applications, sn96.5 /ag3.0/cu0.5 solder is recommended. ? maximum peak temperature of 230 - 240c (below 250c). ? maximum rise and fall slope after liquidous of < 2c/second. ? maximum rise and fall slope after liquidous of < 3c/second. ? maximum time at liquidous of 40 ? 80 seconds. gpio interface all gpios are capable of sinking and sourcing 4ma of i/o current. gpio [0] to gpio [7] are internally pulled down with 100k (nominal) resistors gpio [8] to gpio [15] are internally pulled up with 100k (nominal) resistors.
