yes, you have to convert from 40v to 4,5 v and connect with the yellow and white (just test it with metrics)

I am using the 5v (red and black wires) that goes to throttle. Works very well.

Hello everyone

I thought I would share what I’ve found on the Lime GPS/Cellular module so far. I was given two Lime front green boxes to play with.

The green box contains two boards, the larger board contains the main processor, Bluetooth module, GPS module and voltage regulators. The smaller board looks like it is simply a voltage regulator, dropping the battery voltage down to 5V.

The main chip on the SLT181 board is a MeiG Smart SLM750 LTE (cellular) chip with UART (Serial), USB 2.0, Bluetooth HCI and I2C interfaces. The CPU is a Qualcomm ARMv7 and is running a Linux 3.18 Ubuntu kernel.

The board also contains a SIM card on the bottom. The SIM is from Twilio who offer a “super sim” which can be used internationally to send data via SMS or Mobile data.

I powered the board with a USB to Serial converter connected to the serial pins of the plug. I have included the pinouts that I know so far.
The issue I have is that the chip boots until I get “Error code 303e at boot_flash_dev_nand.c Line 571”
The chip has NAND flash on board so I’m not sure if the error is referring to the on-chip NAND or if it is trying to contact storage elsewhere on the same or another board?

If I drop the Serial TX to earth for 2 seconds at boot, I can put the SLM750 into a programming mode and get an almost full boot. If I earth out Serial TX for 5 second-ish, I get a different boot sequence but both end with a kernel panic and a reboot back to the error code 303e.

The links below are to Pastebin showing the default boot, the 2 second earth and the 5 second earth.

Default boot: https://pastebin.com/PiV3xiGS
2 second earth: https://pastebin.com/eCA5VPx8
5-ish second earth: https://pastebin.com/ed85ceeQ

This is the pinouts of the main plug on the main board.


If anyone has anything to help me get the chip to fully boot I would like to hear from you.

Hello, i have a full boot.

I have a lime scooter. Has extra battery and gps out front. So that is not the newer style others are talking about being different? I got a control board off ebay. I still need dashboard, or I can flash firmware? Seen nothing here about the flash or dashboard part. Please help.

To flash the firmware you need a bluetooth enable dashboard, which is not the case for lime scooter.

Do you know if there is any possibility of using this batteries outside from the original scooter? or using in another scooter (ex.: Lime) as main battery only, connecting one cable from the baterry connectors to the new scooter controller (not as extra battery..)

Salut,
Je voulais savoir, tu as juste remplacé un contrôleur sur une Lime-S et tu as pu t’en servir en mode free ?
Comment tu fais pour déconnecter le GPS ?
Merci

[Bigemul]

Thanks.

Do you think it would be possible to add a battery ?
