E22-400M33S support #16

Open karfam opened 1 year ago

Congratulations on the project

Does the it support the new E22-400T33S due to increased consumption?

Hi @karfam, as I could see from the name of a new module - it's an UART, not SPI (letter "T" in the name). At this point Meshtastic firmware supports only SPI radio modules with letter "M" in the name, like "E22-400M30S", "E22-400M22S", "E22-900M30S", "E22-900M22S".

Yes missed that. Just emailed ebyte to see if they plan a 2 watt SPI module.

@Update They just replied and there is E22-400M33S

karfam commented 1 year ago

According to manufacturer the Consumption of the module is : TX current（mA） 850 1000 1200 Instant power consumption 33dbm

TTGO T-Energy uses SY8089 step down regulator.

TTGO T-Energy Schematic

The SY8089 and SY8089A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 2A output current.

SY8089 Datasheet

Probably the 18650 battery will be fine with the 1.2Amp discharge for a few ms

You need 5V for max power output

3.3V is for some E32 board, like the 20dBm ones and others

Работает - принимает/передаёт, но не понятно какой мощностью, судя по логу - всего 22dB После пересборки FW мощность 2 ватта стала. Пины были поправлены, всё работает.

@kpbicka could you please provide the changes you made in firmware for M33S to the community?

Там надо всего лишь добавить

define SX126X_MAX_POWER 22

также должна присутствовать секция

ifdef EBYTE_E22

define SX126X_DIO3_TCXO_VOLTAGE 1.8

endif

до сих пор никто не знает как вообще всё это работает, но якобы SX1268 даёт 22dBm, а дальше усилитель разгоняет до 33.
