A alto nivel, así se distribuye la energía desde la batería hacia potencia (ESCs) y control:
  • Entrada y distribución de batería 14.8 V (4S)
    • Conectores XT60: J1, J2, J3, J4, J5.
    • Filtrado/almacenamiento en el bus de batería: C6A, C6B.
    • Estas líneas alimentan directamente los ESCs desde el bus “VCC 14.8V Batt”.
  • Conversión a 5 V para la lógica/VSYS
    • Convertidor buck: MP2338 (de 14.8 V a 5 V).
    • Pasivos clave del buck:
      • Entrada/enable: R3, R4 (control de EN y umbral), entrada: C6A, C6B.
      • Conmutación/salida: inductor L1, bootstrap C4, soft-start C5, filtros de salida C7A, C7B, C8, realimentación R6, R7, señal PG con pull-up R5.
    • Aislamiento hacia VSYS del Pico: diodo Schottky D1 desde el “5V Buck Out” a VSYS, con reserva C1.
  • Regulación a 3.3 V para dispositivos de control
    • El PICO toma VSYS y genera 3.3 V (Net “Vcc3v3 Pico”) para los periféricos.
    • Alimentados a 3.3 V: radio U3 (NRF24L01), GNSS NEO-M9N, barómetro BMP280, IMU MPU-6050, con desacoplos locales C2, C3.
  • Dominio de respaldo (solo GNSS backup)
    • Moneda CR1220 V_BCKP a través del diodo D2 y el condensador C6 mantiene NEO-M9N:V_BCKP cuando el principal se corta.
En resumen: los XT60 ([J1]-[J5]) distribuyen 14.8 V a potencia/ESC; el buck [MP2338] genera 5 V, el diodo [D1] alimenta VSYS del [PICO], y el [PICO] entrega 3.3 V a los dispositivos de control.

@copilot can you add a 4g lte modem, one if its available. that doesnt requurea sim card and a sim card slot holder to the entire design. if a sim cardcard is required use a nano sim card slot holder for ithe modem

To incorporate a 4G LTE modem into your drone circuit design, we'll need to consider a few aspects:
  1. Selecting an LTE Modem Module: Most 4G LTE modules require a SIM card to connect to cellular networks. However, some modules support eSIM, which integrates the SIM functionality on the chip itself. Since you're asking for a module that doesn't require a SIM card, an eSIM-enabled module is the closest option.
  2. Power Supply: Ensure that the power requirements of the LTE module are compatible with your existing voltage levels. Most modules operate on 3.3V, so if your module operates differently, we'll have to consider voltage level translation or conversion.
  3. Interfacing: LTE modules commonly use UART, USB, or SPI interfaces. We need to ensure that the Raspberry Pi Pico can communicate with the module via available GPIO pins.
  4. Antenna: Since the U.FL connectors are present, you might be able to use one for antenna connections.
  5. SIM Card Holder: In case we opt for a module that requires a SIM card, a nano SIM card slot will be necessary.
Suggested Steps:
  • Select an LTE module: For instance, the Quectel EC25 is a popular module that would require a SIM card.
  • Add a Nano SIM card holder: Something like the Amphenol SCHA4B0200 can be used.
  • Connections:
    • Connect the LTE module's power and ground pins to appropriate power sources and ground.
    • Use available GPIO pins on the Raspberry Pi Pico to connect to the modem's UART interface for communication.
    • Antenna connections can be made using U.FL connectors already present in your schematic.
Let me know if the Quectel EC25 works for your needs, or if there's another module you have in mind. Once we confirm the selection, we can proceed with detailing the connections further!
