If you want to build your MySondy GO yourself we recommend that you buy this:

Please choose the 433Mhz CP2104 version.

There are two TTGO LoRa ESP32 433 MHz versions:
1) One with a CP2104 chip and
2) another with a CH9102F chip.

Which one is recommended for MySondy Go?

[Thierry50]

hello, I confirm the 2 versions, take the CP2104, I received 2x TTGO with the CH9102F which do not work correctly, my first purchased TTGO is indeed a CP2104 which works perfectly with Mysondy GO

Hi, What is the difference between the CP2104 and CH9102F? I do not know if I am wrong, but as these IC are used to communicate with your computer once connected with the USB cable for programming, the use different serial COM drivers. Do they affect to the received radiosonde signal?

[IZ4PNN]

Hi, no.
The reception of the radiosonde does not change, only the USB driver changes.

hi, to succeed in your prog you must make a strap between the GND and GPIO 0 pins, which you remove afterwards, personally I have less problems with the CP2104 than with the CH9102F,

Hello.
I received today a TTGo with CH9102F chip which was immediately detected by my device manager. The transfer of the v2.30 firmware was also immediate (no need to strap between Gnd and GPIO-0).
The TTGo immediately decoded a remote M10 probe.
A big congratulations and thanks to Mirko, Aldo and all those around them.

Bonjour, normal puisque tu a un CH9102F, il n'y a pas besoin de starp, mais seulement sur le CP2104

[FsixIPO]

Bonjour.
Merci pour la précision !
