Часто, модули с Ali идут без прошивки ESP-AT. В таком виде карта Sprinter Wi-Fi работать не будет, модуль ESP нужно прошить. Инструкция в [документе](Docs/ESP-module-flashing.pdf). Часто, модули с Ali идут без прошивки ESP-AT. В таком виде карта Sprinter Wi-Fi работать не будет, модуль ESP нужно прошить. Инструкция в [документе](Docs/ESP-module-flashing.pdf).
## Изменения ## Изменения
* _v1.0.3_ Устранена ошибка с перепутанными сигналами RTS и CTS. В [документе](Docs/rts-cts-fix.pdf) описано, как это исправить на старых версиях платы. V *1.0.3* Устранена ошибка с перепутанными сигналами RTS и CTS. В [документе](Docs/rts-cts-fix.pdf) описано, как это исправить на старых версиях платы.
* _v1.0.4_ Добавлен контакт VCC на разъеме X2 для подачи напряжения 5В при программировании ESP через внешний USB-TTL UART адаптер. V *1.0.4* Добавлен контакт VCC на разъеме X2 для подачи напряжения 5В при программировании ESP через внешний USB-TTL UART адаптер.
* _v1.0.5_ Косметические изменения для удобства пайки.
