BOM Alternates
Major parts and alternatives for the FLIP_C3
The retail version of the FLIP_C3 is currently manufactured by JLCPCB using their parts library. While it is said that JLCPCB uses their sister company LCSC for parts, the two companies usually have different stock. This is a living document of potential alternates for major parts including those used in production or considered for production. This document can be used in case of stock declines or discontinuation of parts. Basic passives like resistors and capacitors may not be included as this is intended for major functional parts and those parts can be easily replaced with a simple search when using the BOM directly from the EasyEDA files.
I2C & UART Connectors
For Qwiic and Stemma QT compatibility we use JST-SH1.0 connectors based on SM04B-SRSS-TB(LF)(SN) via reference document from Sparkfun
A second connector is used to connect to the RX/TX lines on GPIO 20/21 alongside GND & 3v3 in the same order as the I2C connections on GPIO 1/0 - See PINOUT
ESP32-C3
There are two variants of the ESP32-C3-MINI-1 module. The H4 variant has a higher temp tolerance than the base model N4. We've focused on using the H4 variant, but supply chain issues could lead to us using the N4 model in some production runs. Our early 2024 production run may require this change.
