Open karfam opened 1 year ago
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
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.
The SY8089 and SY8089A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 2A output current.
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
У меня модуль E22-400M33S SX1268 433/470MHz 2W SPI Chip LoRa Module

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
также должна присутствовать секция
до сих пор никто не знает как вообще всё это работает, но якобы SX1268 даёт 22dBm, а дальше усилитель разгоняет до 33.
Congratulations on the project
Does the it support the new E22-400T33S due to increased consumption?
