+**New in Version V1.8a**
+
+- Added C1, C2, C3 footprints. It's to add capacitor to poor 3.3V VOut of esp32 on board regulator. This one is not output filtered enough resulting sometimes with brownout reset loop. Now you can plug radial or 1 (or 2) SMD 0805 in parallel

 **New in DMA Version V1.8**
 
 - Removed ESP8266 compatibility, since DMA need more GPIO it's now exclusive to ESP32 boards with WeMos Mini D1 wiring called ESP32 Mini Kit or ESP32 Wemos, or ESP32 MH-ET Live such as this [banggood model](https://www.banggood.com/Wemos-D1-Mini-ESP32-ESP-32-WiFiBluetooth-Internet-Of-Things-Development-Board-Based-ESP8266-p-1205854.html) or this [aliexpress](https://www.aliexpress.com/item/MH-ET-LIVE-D1-mini-ESP32-ESP-32-WiFi-Bluetooth-Internet-of-Things-development-board-based/32815530502.html). But you can find a lot also on ebay, not a problem.
 - PCB board has been extented to fit this ESP32 Mini module .
 - LDR to dynamically change brightness according to ambiant light
 - I2C connectors as header and Groove to plug a bunch of sensors
 - Added one touch pad button
+- No need to wire back the shield to HUB75 output of the Matrix Panel

 Looks like PCBs.io is gone, I do not have any rewards from PCBs.io since August 2020 and my free order placed after are still not received, so my guess they are not on business anymore and my $1000 rewards are not usable anymore, too bad.

 It's a pitty after several discuss with OSHPark that I can't have any rewards for each people ordering my boards, this would allow me to order free PCB for shared projects and create new ones. For information my shared boards generated a total of **$285 162.00** orders at PCBs.io in 4 years, not bad at all :-)
