Project prototyping board for ESP8266 - 2"x4", w/plenty of Through-hole and SMD prototyping area + power supplyDesigned by Azduino by Spence Konde in United States of America
Somehow my whole inventory of almost everything got zero'ed out. No wonder nothing was selling, I'm working on correcting this.

Similar to my other "project boards," this board combines outlines for an ESP8266 and power-supply circuitry with plenty of prototyping space for SMD and through-hole parts. This enables rapid prototyping of projects involving the ESP8266, as well as being well-suited for unique or nearly unique parts for home hobby projects. By integrating common SMD footprints on the prototyping board itself, the need to use breakout boards is reduced, and by using real soldered connections (as opposed to solderless breadboard), reliability is greatly improved, and the project can be moved around without worrying about wires getting pulled out (and who hasn't tried to show off their breadboarded project, only to be left fumbling around looking for the loose wire, as witnesses look on).
Now available with the modules mounted - this is done with lead-free solder, making the assembled boards ROHS too!
This board features pads for an ESP8266 in the ESP-07 or ESP-12/12E/12F modules on a 2" x 4" board (same outline and hole location as my general purpose 2"x4" boards). All the GPIO pins, and the ADC pin, are broken out to groups of through-holes along the bottom edge. The power supply section can use an SOT-223 regulator with one of two pinouts (only one regulator at a time): either the 1117-series ones, with VOut on the tab (using the outline on the top of the board), or the other pinout common for many lower-dropout regulators, with ground in the middle (using the outline on the bottom of the board).
Input and output caps can be either 1206 SMD caps or through-hole caps - pads for both are provided for those who don't like SMD soldering (soldering SOT-223 is easy - easier than soldering down the ESP8266 - so I didn't include a through-hole regulator option). The ground and Vcc lines are routed around the board with nice, thick traces, so you're never far from power and ground, and Vin is accessible in two points as well, including right in the middle of the SMD prototyping area to supply any level-shifting IC's you may need.
Since getting these made, I've incorporated several of these into projects already. (Note that the boards pictured below are a prototype version with a different silkscreen - the silkscreen on the boards available for purchase is exactly as shown in the main product picture above.)
APA102 driver - this uses the ESP8266 to drive a string of my Ping-Pong Ball Lights, and provide a web interface for adjusting the colors. Preset color patterns and animations are stored on an AT24-series EEPROM. Level shifting for the ESP8266 is achieved with a pair of low voltage MOSFETs (5LN01SP - yes, a through-hole MOSFET that works at Vgs=1.5v) and external pullup resistors. A 1117-series regulator provides 3.3v from the 5v supply (which powers the LEDs).
Router Rebooter - Two relays, screw terminals, and FETs to drive them. This is being used to resolve a persistent issue with a router and modem at a remote location, which is regularly monitored using webcams. Periodically, the router (or modem - we're not sure which) will crash, and it'd be a 1-hour drive each way to get there to reboot them. To solve this problem, this router rebooter has two NC relays which turn off the router and modem, respectively. The software will ping a high-uptime website periodically, and if it is unable to access it, it will automatically use the relays to power-cycle the router and modem. A 1117-series regulator provides 3.3v from the nominally 12v input.
ESP32 version of the same boards - improved with ENIG gold surface treatment for unambiguously lead-free assembly, if desired. (personally I like leaded solder, but a lot of people don't seem to).

International orders have been suffering long delays due to COVID-19 - please check your country at https://about.usps.com/newsroom/service-alerts/international/ and make sure that I can ship to you, and that you are okay with any delays. There may be additional information available from your national postal service. Some customers have reported packages being delayed in transit by over a month. We cannot offer any sort of guarantees regarding international shipments at this time; we apologize for the inconvenience, and are looking into shipping internationally through UPS.
Please be sure that the address given to Tindie is accurate, and includes your street name and number - company name is only required if shipping to a commercial address. International orders require a valid phone number.
Domestic packages that go more than 1 week without a tracking update will be presumed lost in the mail and refunded or reshipped as buyer prefers. Any international packages can be delayed in customs without warning for 2 weeks or more. After 1 month without a tracking event (2 months to South and Central America - insane delays in those nations are commonplace), we will reship or refund a missing order (as you prefer). COVID-19 update: Some countries have stopped processing incoming international mail entirely -we will cancel orders to countries which we know are not processing international mail at all. This may also cause longer than usual shipping times - we are not responsible for such delays.
We do not open inquiries through the postal service - experience has shown this to be futile.
We ship all orders via USPS. UPS will be added as an option in the near future, I hope. We do all shipping through Stamps.com, and they offer me UPS, but all addresses are rejected as invalid, and I have emailed support numerous times and have had zero response. So at present, we cannot entertain requests to ship through other carriers.
We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
