Velmi vážná chyba v návrhu desky !!!

Velmi vážná chyba v návrhu desky !!!
Ondřej Doležal
TTGO v2.1. 1.6 má chybu v nabíjecí části desky, kdy 5V z USB portu je přivedeno přímo na připojenou Li-Pol baterii !!!
To znamená, že je možné připojit baterii, ale V ŽÁDNÉM PŘÍPADĚ nesmí být zároveň nabíjena !!!
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.

Dobrý den, děkujeme za informaci, zkontrolovali jsme skladové zásoby a všechny kusy, které momentálně máme jsou v pořádku – mají diodu, ne pojistku. Pouze ve fotkách máme převzatou chybnou fotku s pojistkou, fotku změníme.
