Instrucctions of how to set it up properly

Hi,

I received the ESP-32 Rev 2. Shipemnt was OK and it has included a litle origami. Many thanks.

I have just powered it on and I see the first screen at the OLED display:

ESP32
PCM5012 BT speaker
my device name is hogehoge_mont
Yeah! Speaker!


But I do not know and I was not able to find out clear instructions of how to proceed to have it working.
This is my first experience with ESP32 so I´m not sure what I´m missing.
I will appreciate more details. Thanks

Hello! and thank you for review!
First of all, please install
https://github.com/espressif/esp-idf
, where the setup procedure is explained in the page above.
After finishing it, please copy the source code by
https://github.com/kodera2t/ESP32_OLED_webradio
by
git clone https://github.com/kodera2t/ESP32_OLED_webradio
and execute "make menuconfig" and set your SSID and password will make your board into web radio.
Please try!

Amazingly fast shipping, double protected

I received the package today after only 8 days. You should know that this never happens with Romanian postal service.
I was happy to find the board in a sealed water-tight anti-static bag, next to the color-printed instructions and a nice origami star, all put in 2 airbubble-padded envelopes, one inside the other.
I am out of nice words to describe how happy I am with this seller, the product and overall experience.

Thank you!
Florin

I am so happy to see your satisfaction!! Indeed shipping time takes sometimes close to one month but in the best case it just take around one week, so the best case came to you, great! Please enjoy wonderful ESP32 world with sophisticated high resolution TI's DAC PCM5102A. Thank you!!

how to get started with esp32-adb

Hi I just bought the esp32-adb board (REV.2) couple of days ago. AFAIK, there is no need of a lipo charger. But I could not sketch a simple app like "hello world" to the board. The following error has occurred:

"A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header"

Do you have any idea how can I fix it?

By the way, it was really fast shipping. Thanks for great product.

PS: I made it working by changing usb cable. Thanks a lot for your help.

Jackie

Sorry for overlooking your review.
Can I ask you to give me more details about your problem (which environment, ESP-IDF or Arduino IDE) and also what kind of program, "hello world"? All of ESP32-ADB are tested before shipping and correctly writing Bluetooth speaker mode example so I would ask you try
(1) change USB connector of your computer
(2) change USB cable (sometimes works)
and also switch off-on before uploading your new binary. The test firmware (bluetooth) might avoid your new binary uploading (in rare case it happens).
Here in the review column we cannot make conversation so please let me know the result in Tindie's messaging system ( you can send me in tindie's system). Thank you

Good product

I like it, but it is a bit less sensitive on wifi due to the implementation of the antenna.
Much less sensitive than other esp8266. No other experience with an esp32.

Response from microwavemont | Aug. 21, 2017

Hello and thank you for review. The PIFA antenna part of ESP32 should be ideally "hanged from main PCB" but I did not take this configuration for better stiffness of the unit. But thank you for suggestion and I may reflect it on the next items!

Per-Olov | July 20, 2017

Excellent for prototyping!

I needed a board that had an ESP32 and a DAC of any sort on it, this did it all, including a display and the possibility to run off a battery (with charging circuit and all)

It did take a few minutes to understand why it didn't start or program the first time, but that was because i totally missed the fact that there was a power switch on the board :)

Response from microwavemont | July 21, 2017

Thank you so much for reviewing and I am very happy to see your satisfaction. The main switch is added for Lipo battery operation and I may need to change the circuit in the case of USB-bus power, main switch can be by-passed (in the case of bus power operation, the board can be always on.) Anyway Thank you so much!

Nice developing board

Thank you Toshiro,

Great product! Software on GitHub works without problems, nice documentation, fast shipping.

Perfect quality. Recommended

Response from microwavemont | July 21, 2017

I am very happy to see your satisfaction. YES, indeed I believe ESP32 + PCM5102A, a very high quality audio DAC is a kind of "best partner"! Please enjoy wonderful combination. Thank you so much!

Benjamin | June 20, 2017

Perfect

Fast shipping, well packed, included documentation, well product, with origami.

ESP-IDF Software on Github works out-of-the-box.

In short: Perfect japanese quality

Small thing to improve: make a ground plane. This would propably improve the noise level.

Response from microwavemont | June 21, 2017

I am really happy to read your satisfaction to ESP32-ADB! YES! As pointed out, by the sake of Espressif's esp-idf and TI's PCM5102A and powerful ESP32 module, ESP32-ADB works very well!! Thank you so much for review!

Andrew | June 19, 2017

Great developer and product !

Great little ESP32 audio development board and it works. Toshiro responded to my questions immediately and is highly recommended. The ESP32 and PCM5102A are awesome chips.

Response from microwavemont | June 19, 2017

I am very happy to read your satisfaction to ESP32-ADB!! Indeed ESP32 is enough powerful by dual-core processor and TI's PCM5102A is famous Burr Brown originated sophisticated high resolution audio DAC!! Thank you!!

Oleg | June 14, 2017

Nice device and excellent seller!

Thank you, Toshiro, for this board.
First of all, I bought this item for streaming music from iPhone6 in the car, where I have AUX input only.
ESP32-ADB it's really small plate, less than expected and you can put it everywhere. Very quick start of working, simple connection via bluetooth.

1. Sound: comparing with iphone 6 approximately the same quality, not better/not worse.
2. Delivery: from Tokio to Moscow just 7 days. Wow!)
3. Package: Very well packed, you may not worry about safety. User manual is included.
4. Seller: Recommended! Quick response and nice to talk.

Response from microwavemont | June 14, 2017

I am very happy to read great satisfaction and quick delivery to Moscow. Indeed shipment to Russia generally takes two to three weeks and sometimes more than one month but this time just seven days is really "lucky" case!! Also I am very happy to read "good and practical utilization" of ESP32-ADB in car!! TI's PCM5102A has high resolution and provides very good sound and really car usage is good application. Thank you so much!!
