In terms of the power switch, we have changed the switching interaction mode. The added SMA antenna can enhance signal transmission.Package included: 1 x TTGO LoRa32 V2.1 868Mhz Module2 x Pin1 x Antenna1 x Power Cable(Notice:The shipping list does not include battery and SD card)About the lipo charging circuit problem (Important update in 10th September 2018):

After V2.1-1.5 was upgraded to V2.1-1.6, after our tests, the diode components should be used on the charging circuit, but we used a fuse, the diode is unidirectional, and the fuse is bidirectional. This causes the USB voltage to pass directly to the battery. After a long woking time, the battery may become hot or burn, so you cannot use this V2.1-1.6 version to charge the battery! ! ! (Battery can be used, but the battery cannot be charged)

If you want to use this V2.1-1.6 version to charge the battery, you need to replace the fuse in the figure with a diode (Type: BS5819 SOD123 1A) to use the charging function normally. The following is an upgraded picture.
