Buscamos un diseñador de una PCB para un telefono GSM para emergencias. Al pulsar un interruptor se efectua una llamada a un numero prefijado, si este no contesta se llama al siguiente, así hasta 5 números diferentes y enviará un SMS a un solo número para avisar de la emergencia, al acabar la llamada también cortará la tensión de la batería incorporada para no tener consumo. Hemos pensado en un arduino ó un attiny85 con una SIM800L o similar con un pequeño amplificador de unos 5W para oir la llamada en exteriores. Necesitamos archivos Gerber.

Buen día, soy ingeniero mecatrónico tengo experiencia con microcontroladores attiny, atmel, esp32, esp8266, stm32, teensy entre otros, para su proyecto se puede usar el modulo sim800l este modulo es 2G debe tener en cuenta que algunas operadoras ya no trabajan bajo esta red, propiamente el attiny85 no tiene serial nativo pero se puede usar la opción de software serial para la bocina se conectara directamente al modulo sim800l, cuento con todos los componentes por lo que podria comenzar de inmediato, se entrega la programación delattiny85 y archivo gerber del diseño. Podemos tener una reunión para dar mas detalles sobre las especificaciones del proyecto, Quedo pendiente de su respuesta, saludos.
