Connect an FPGA’s XM105 Debug card to SPI over RJ45 LVDS.

Designed for 208mil SOIC-8 footprint, though has some leeway. Specifically targets Winbond flash memory. By DaedalusRising using Altium Circuitmaker

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"
