LoPy4, Power Amplifier
-
Hello,
I wonder if LoPy4 comes with a power amplifier. If there is, does it serve for all the four modules namely WiFi, Bluetooth, LoRa and Sigfox?

@justin AFAIK the answer is NO. And be aware, that WiFi and Bluetooth is driven by an ESP32 chip, whereas Sigfox and LoRa is driven by an SX1276 device. The SX1276 has an internal power booster, but I'm not sure whether it is used.
Besides that, the maximal power is subject to national regulations, and the Pycom obey these. -
@robert-hh Thanks for the reply. You mentioned "Sigfox and LoRa is driven by an SX1276 device. " Is Sigfox driven by SX1276? I thought sx1276 only supports LoRa.

It is. The SX1276 can also provide the modulation required for Sigfox, even if that may not have been the primary focus.
