Features:OOTDTY Compared with T7-V1.4, the two pin GPIO16 and GPIO17 that cannot be used for external expansion are replaced with GPIO25 and GPIO27 that can be used to define functions, so that they can be for those expansion board of miniD1, and are not affecte by original GPIO16 and GPIO16. GPIO17 pin impact.
Radio frequency: with -97dBm sensitivity NZIF receiver Class-1,Class-2&Class-3 emitter-AFH.
