W8BH Morse Tutor (ESP Rev 2B) PCBs #esp32 #pcb


 

Greetings,

The ESP32 Rev 2B PCBs that I ordered from JLCPCB on 20 DEC 2019 arrived today, 13 days later. That is ten days faster than my first PCB order from JLCPCB. I chose the Economy shipping option this time as well. I was trying to beat Chinese New Year, which is on the 25th of January 2020. Evidently, China businesses shut down for Chinese New Year Holidays because everyone goes home. 'Home' for the Chinese living in the city is usually somewhere in the country. Anyway, this year I beat Chinese New Year.

These are beautiful boards! Thanks Bruce! You are a Gentleman, a Scholar, and a fine Craftsman as well. I hope that one day I can make such a nice board using KiCad. You worked F.Cu as well as B.Cu. Well done!

These PCBs are 100mm x 98mm. They are double sided. There are two choices available for the display. I can mount either a 3.2" TFT display on the board, or a 2.8" TFT display on the board. It looks like the display, the Volume knob and the Rotary Encoder are mounted on the front of the board. The Speaker, Audio Jacks, Barrel Jack, Amplifier module, and Mini-360 buck converter are mounted on the back of the PCB.

The silkscreen layer is very sharp looking, easily identifying where each component and module needs to be placed. I am looking forward to putting a couple of these boards together. I will have to order a couple of displays first, so it may take awhile before I can show a finished PCB.

Total cost for five PCBs, including shipping and handling was $8.64. That comes out to be about $1.73 per board. I already have everything, except the display module. So I'm going to order those today. I am leaning toward the larger display because these old eyes need all the help they can get. (8>{D=

Ken,

The boards look great!
Are any available for sale or are they all spoken for?

Thanks for letting me join the group.

All of these boards are spoken for. Sorry.

Today I ordered two 2.8" 240x320 TFT SPI ILI9341 displays with SD card holders.
I expect to wait several weeks before they arrive from China.
I hope I beat the Chinese New Year Holiday.

Kevin (K3TL)
I have extra boards of both releases.?
Email me off list wb2art@... if interested.
Ken WB2ART?


 

Two 3.2" displays arrived today, the 16th of January. They were shipped from China on the 4th of January, so that took about 13 days. Not bad. Plus the tracking for this package was very good. I cannot say the same thing for the 2.8" displays I ordered on the same day, which, as far as I can tell, are still somewhere in China.

I will start building the ESP32 Rev 2B PCBs tomorrow.

Ken,

Can you provide a link to where you ordered the 3.2" displays?

i ordered one off epay and it arrived today, but has the wrong connector, likely as it is touch capable.

Hello Kevin, K3TL,

I ordered two of these 3.2 inch displays:

You can compare what you got with that one?

You may want to wait until I build my first ESP32 PCB to see if the ones I ordered work?
I will be posting my build notes to this thread.

Thanks Ken,

The pin-out of yours looks correct for the board.

The one i ordered wont go to waste, i can use it in another project.

I will wait to hear if yours works before ordering.

Greetings,

I just finished the first W8BH Morse Tutor (ESP32 Rev 2B) board and posted a short clip on YouTube:

I am building two at the same time, following the excellent Build Guide, located at:



When I am finished adding the audio section to the second board, I will post some Build Notes.
