I have developed a circuit and a printed circuit board in the EasyEDA program . But due to the fact that there is an error in the database with the numbering of the atmega16a-au microcontroller pins between the circuit and the footprints, the printed circuit board I ordered was writing with incorrect connections to the microcontroller, as a result, I lost time and money. No one answered my letter to EasyEDA support. no one returned the money or even apologized. Therefore , I warn all users of the EasyEDA program . Be careful and double-check your schemes with the help of the utilities. Otherwise, you will have the same problems as me and no one will compensate you for the loss!!!
