It is a very powerful development kit because it allows you to assemble your solution with all the elements already installed. The liion battery holder is a plus. The included sketch is in scan mode of nearby wifi networks. The revision of the board received is 3.0 and the circuit diagram can be downloaded from http://myosuploads3.banggood.com/products/20190830/20190830005003t18v3.pdf. The red LED indicates power to the board, the green network warns when the battery is charged. The battery charging current is 875mA. The TPA5400 DC/DC converter reaches a temperature of 49ºC when it is charging the liion battery, but it is within limits. The consumption of the circuit charging the battery (discharged) and the active wifi part is 1.2 Amp. Of all the modules that I have bought for development with ESP32 this seems to me the option with more advantage to have accessible JTAG as well. In short, a very good option for development with PlatformIO or ArduinoIDE.

The unit is very compact with the bateery holder ready for liion, battery. I'm testing the unit, here are my impressions. SIM7000G. (Global) it's a low-power cellular module that supports the new LTE CAT-M1 and NB-IoT technology and also has integrated high-speed, multi-GNSS (GPS, GLONASS and BeiDou/Compass, Galileo, QZSS standards) for location tracking. This version can be used around the globe countries. More information can be found in https://github.com/botletics/SIM7000-LTE-Shield GPS Module. It fixes the geo position very slow the first time (it depends of your coverage of course) took 2 minutes in my case. Pros. - USB C - SDCard socket. - 18650 backup power supply - JTAG points to debug. - Additional Solar Cell voltage input. - Espressif ESP32 WROOVER-B with 4 M Flash, 8 M PSRAM Cons. - No documentation, you have to explore groups and forums for each new element built in. - No github or repository to inspect the sketch built in. Yo have to flash and everything is lost. - Price.

Finalmente lo he recibido despues de 1 mes y medio desde el envío. Es una ESP32 sin mayores variaciones sobre el diseño estándar y con las especificaciones del pinout normal. Lo que no entiendo es porque el programa con el que viene cargado no está disponible como sketch. Sería de agardecer el que pasaran el sketch con el que viene cargado para comprobar el funcionamiento porque simplemente, no se lo que hace y tampoco sirve de mucho porque lo he de flashear de nuevo. Alguien sabe si la parte de GSM con el SIM800L es compatible con con la red de Pepephone gprs?

A very compact unit with less GPIO than the Dev kit versions oriented to Graphical Display environments, but usefull without any doubt. The addon for external battery connection saves many headhaches if you plan to use it as a portable device like as I planned. The USB C connector it's a +.

The battery authonomy was short after first charging, you need to repeat charging cycle 3-4 times to long last time.
