LED Bias Board for SY’s Red Light District

ESP-01 & ESP-03 Breadboard Breakout

Provides voltage regulation and switches to enter programming mode (over FTDI or serial UART).

Goal

Provide a simple-to-use programmer for ESP8266 modules similar to Adafruit Huzzah ESP8266 module.

Changes in v1.5 include: No ground plane under antenna, mounting holes, clearer layout, labeled header for ESP-01, resized board to accommodate entire length of ESP-01.

Usage:

Solder all components on, including your choice of ESP-01 or ESP-03. Insert UART connection into header at end of board. S1 will reset the board. To program board, hold S2 while hitting S1. S3 will select between 3.3V and 5V input on Vin (towards the ESP module is 5V).

Schematic

Schematic, BOM, and Ultiboard layout files can be found at the github repo.

Components:

U1 can take either castellated SMD pads (ESP-03) or a 2x4 .1" pitch female header (ESP-01).

R1-R4 = 10k 0603, R5 = 1k 0603.

C1&C3 = 10uF 0805, C2 = 0.1uF 0603.

LED1 = LTST-C190KFKT Orange 0603 LED.

U2 = LD1117AS33 3.3V 1A Voltage Regulator.

S1-S2 = KMR221NG LFS pushbutton momentary SPST switch. S3 = PCM12SM SPDT slide switch.

Mounting holes provided are for #2 US screws (0.090" diameter). The spacing is 1.4" vertical, and .8" horizontal.

The breakout headers are spaced at 0.8"

Prototyping Shield for Arduino Micro with SMD footprints SO08, SOT223 and SOT23

Have you ever been frustrated creating a prototype using a simple MOSFET or 8-pin chip that’s only available in SMD? This Micro Proto Shield is the answer, for the Arduino Micro platform.

Information on the board

All Arduino pins are labelled on both sides of the board. The Arduino symbol and the ISP header outline are provided to help you plug in the Micro the correct way around.

All wires to the SMD footprints are shown in white on the silkscreen so you can quickly see which hole connects to which SMD pad.

N-channel MOSFETS connected to PWM pins

The two large MOSFET footprints Q1 and Q2 are already connected to the first two PWM pins (3 and 5) on your Arduino. Source is connected to grounds and the Drain output has a prototyping hole connected to the large tab on the transistor.

The transistors require pullups to hold them in the off state while the Arduino bootloader is active. Footprints for 0603 size resistors are provided for R1 and R2. Or you can wire through-hole resistors to the pads adjacent to pins 3 and 5.

If the pinouts on your transistors are different, just cut the resolderable traces between the holes and wire them up how you want.

SOT23 footprints

The large SOT-223 transistors have enough space inside their footprint to include pads for SOT23 size transistors too: Q3 and Q4. The wiring is the same as common N-channel MOSFETS or you can cut the resolderable traces and wire it however you want.

SO-8 integrated circuit U1

This seems to be a common size for memory chips, thermocouple interfaces and a lot of other different chips. All 8 pins are broken out to holes, with no default wiring. Connect your chip any way you want.

95 free prototyping holes

There’s still a large number of free holes on the board, so a 14-pin DIL chip can be installed or anything else that fits. +5V and ground buses are provided at both ends of the board.

Check out the standard prototyping version too

I’ve also shared a version without the SMD footprints, if you need more conventional components.

Flexible prototyping shield for your Arduino Micro.

Only 0.2" longer and wider than the Arduino Micro. 139 holes ready for your components to solder in.

0.1" hole spacing will accept standard ICs, breadboard headers, DuPont connectors, TO220 transistors and more. Extra +5V and Ground rails are provided at both ends of the board. All Arduino pins are connected to two adjacent holes, with cuttable and resolderable jumpers. Every pin is labelled on both sides of the board.

Mounting holes are 2mm. Can be drilled out to 3mm or 1/8" if required.

The Arduino “infinity” symbol and the ISP outline is included to help you plug in the Micro in the correct orientation. It could fit both ways but then the labels will be wrong.

Also check out the SMD version that has some surface-mount component outlines available.
