There are dozens of consumer routers that can act in "station" mode to bridge a wired network to a wireless AP. Costs $15-30.
Getting one of these is much quicker and easier and cheaper (when you account for labor) than building your own.

It's a good habit to always order multiple parts, especially when shipping is slow, in case you get a DOA.

Have you tried programming your ESP32? There is a small chance that your LED, and not the entire board, is defective.

Have you considered using an ESP32 with an external antenna? External antennas are inexpensive and provide significant range boost.

For example M5stack uses EA3036 Odroid-go uses MP2161 Olimex ESP32-DevKit-LiPo uses Silergy SY8089 Thanks. Very helpful. For the benefit of others: The EA3036C is under $0.15 per unit The MP2161 is under $0.10 per unit The SY8089 is under $0.09 per unit Perhaps luisonoff will be interested in analy...

You can use LiFePO4 battery instead of Li-ion without any LDO.

Thanks for the idea. Even a LiFePO4 battery has a voltage which is too high while it is charging.

There are a lot of boards that support batteries and charging and publish the schematics, check them out. Thanks. All the ones that I reviewed use LDO linear regulators. They are inefficient because of the power loss for regulation AND the relatively high required battery voltage. Do any boards tha...

The ESP32 is intended to be suitable for low power applications - in other words, running on batteries. The optimal voltage for the ESP32 is 3.3V. The nominal voltage of a Li-ion battery is 3.7V but it can be anywhere between 3V and 4.2V. Many of the development kits come with the AMS1117, which has...
