Please find the attached responses inline in green.</span></p><ol type="1" start="1"><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">Please don’t call this "OVMS v4", as that would cause confusion. Our ‘v’ naming is based on processor architecture:<br clear="none"><br clear="none">v1 - original prototype hand-built (PIC18F2680)<br clear="none">v2 - first production version (PCI18F2685)<br clear="none">v3 - refined production version (ESP32 WROVER, 16MB flash 4MB SPIRAM)<br clear="none"><br clear="none">Within that we have a .x naming scheme for subversions. The current version is v3.2 and the upcoming 4G module will be v3.3.<br clear="none"><br clear="none">It sounds like you are trying to make a different layout of the upcoming version, so perhaps a fork of v3.3?<br clear="none"><br clear="none">My concern here is to avoid confusion. <span style="background:lime;">Yes this is kind of fork of v3.3 with some additions on v3.2. </span></li><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">SIM7600 sounds ok. That is the direction we are heading as well. <span style="background:lime;">If we adopt the version SIM7600G-H then this is global with all regions supported. However all modules on this series are pin to pin so doesn’t matter if we go for region specific.</span></li><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">For ESP32 are you using WROVER module with 16MB flash and 4MB/8MB SPIRAM? <span style="background:lime;">Noop. I am planning to use wroom only. Should I switch to wrover instead?</span></li><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">For things like ACC detection, full power control, RGB LED, which GPIO / extended-IO pins are you using? <span style="background:lime;">I have used extender i.e MAX7317AEE+. Attached is the reference for esp32 connections.</span><span style="color:windowtext;"> </span><span style="background:lime;"></span></li></ol><p class="yiv6507036826MsoNormal" style="margin-bottom:12.0pt;margin-left:36.0pt;"><img id="yiv6507036826Picture_x0020_1" style="width:11.9166in;min-height:4.9in;" src="cid:59JXqbtYfgY6J73obPKY" yahoo_partid="1.2" width="1144" height="470"><span style="color:black;background:lime;"></span></p><ol type="1" start="5"><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">It doesn’t look like you support the current expansion board option? <span style="background:lime;">Noop. I am not using any expansion thing here. Any particular requirement for that?</span></li><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">It seems that you are using a different vehicle connector, so this will be hardwired for Indian MG ZS EV? <span style="background:lime;">Noop. Since we can use this for many other vehicles also by changing the connector. In current version the PCB has exposed pads where we need to solder wires to connector.</span> </li><li class="yiv6507036826MsoNormal" style="color:black;margin-bottom:12.0pt;">Note that we removed the LED in v3 (it was in v2) due to power consumption issues with that. <span style="background:lime;">There is power control option from hardware side. Only esp32 and accelero module are always on. For other things, power control is done from GPIO of esp32.</span></li><li class="yiv6507036826MsoNormal" style="color:black;">How are you intending to handle firmware? A fork of the current code, or kconfig flags to support your hardware differences? <span style="background:lime;">Unfortunately I am not that good on software side . Can modify it slightly by not much. Would require some support on this .</span></li></ol><p class="yiv6507036826MsoNormal" style=""><span style="color:black;background:lime;">One more thing, I was not able to find the CAN ic in stock so using TCAN334 from TI. Will this work with MCP2515-E_ML?</span><span style="color:black;"></span></p><p class="yiv6507036826MsoNormal"><span style=""> </span></p><p class="yiv6507036826MsoNormal"><span style="">Regards,</span></p><p class="yiv6507036826MsoNormal"><span style="">Rohit Soni</span></p><p class="yiv6507036826MsoNormal"><span style=""> </span></p><div><div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm;"><div class="yiv6507036826yqt1950719302" id="yiv6507036826yqtfd53930"><p class="yiv6507036826MsoNormal"><b><span lang="EN-US">From:</span></b><span lang="EN-US"> OvmsDev <ovmsdev-bounces@lists.openvehicles.com> <b>On Behalf Of </b>Mark Webb-Johnson<br clear="none"><b>Sent:</b> 09 August 2021 01:51 PM<br clear="none"><b>To:</b> OVMS Developers <ovmsdev@lists.openvehicles.com><br clear="none"><b>Subject:</b> Re: [Ovmsdev] OVMS Hardware 4.0</span></p></div></div></div><div class="yiv6507036826yqt1950719302" id="yiv6507036826yqtfd43336"><p class="yiv6507036826MsoNormal"> </p><p class="yiv6507036826MsoNormal"><span style="color:black;">Looks interesting.
